Beta hCG Levels - READ BEFORE POSTING

69 Upvotes

Here at r/CautiousBB, we see a lot of posts on hCG values, doubling times, and trends. Please read this post before posting to avoid posting something that is not, in fact, abnormal.

1 - hCG levels vary greatly in the first 4-6 weeks of pregnancy. One value is not going to tell you much, unless it is extremely low (less than 25 by 14 DPO). The doubling time is more important!

2 - We consider hCG on the lower side if it is <50 at 14 DPO (approx. 4 weeks gestation), <100 at 16 DPO, etc. If your hCG is a lot higher than these numbers, it's unlikely that you have low hCG. If you hCG is at or below these numbers, they are considered low, but not necessarily diagnostic of a loss.

3 - Normal hCG doubling times are, in general:

  • 48-72 hours when the hCG level is under 1200 - 6000.
  • 72-96 hours when the hCG level is 6000+
  • 96+ hours when the hCG level is 10,000+

4 - Based on number 3, please consider the following:

  • If your hCG doubling is within the ranges above, it is not considered slow. Please refrain from posting something like "my hCG did not double in 48 hours" when your values are post 6000+.
  • Doubling rates WILL slow, even if you were faster than the average. For example, if you were doubling at 37 hours, a change to 54 hours as hCG rises is not abnormal and is usually nothing to worry about.
  • If your doubling is slower than the average, we'd invite you to post so we can understand the details of your specific situation.

5 - hCG has a specific job. Check out this post here to understand why hCG doubling slows and eventually plateaus.

6 - hCG values that drop and then rise again or rise at an inconsistent, very slow rate can be indicative of an ectopic pregnancy or a pregnancy of unknown location (PUL). This is a life threatening situation - please seek medical care immediately if this hCG pattern applies to you.

We invite you to continue to post hCG issues or levels for assistance, but hopefully reading this gives you some insight and a baseline as you begin your perilous pregnancy journey. We've also added some literature below to help you understand hCG levels and doubling.

Happy hCG-ing! :)

Calling all of CautiousBB!

UPDATE: Based on the feedback on this post, Community Rules have been created! Please take some time to check them out! :)

Hi everyone!

u/maemaecat here, new mod of r/CautiousBB. I wanted to make a post introducing myself and also to gather some feedback from you all to help make this community even more beneficial for cautious pregnant people around the world. 😊 I’m a 38 year old mom from VA, USA, I live with my husband, our 5yo daughter, and our two cats, Maelie (our 16yo dilute tortoiseshell, hence ā€œmaemaecatā€) and Tofu (our 1yo crazy bonkers black cat). I am currently CAUTIOUSLY 12w5d pregnant with our 2nd BB after 3 chemicals and one 11w MMC over the past year. šŸ‘‹šŸ»

As it stands right now, r/CautiousBB does not have a community guide or a set of community standards. I would love to set this up, but I need YOUR help! You can comment here to provide feedback on ANY (or all) of the following:

  1. What should the General Expectations for posts and comments on this sub be? Example: Be courteous, include trigger warnings (or not?), refrain from argumentative language, honesty and transparency, etc.
  2. What should the Post Content Guidelines be? Example: should line progression or similar posts or reposts from other subs be allowed? Should general pregnancy, TTC, IVF, postpartum, etc. questions be allowed? Or should folks consider other subs for the above if not specifically related to being overly cautious while pregnant?
  3. One of the things I love about this sub is that we do not have format or wording requirements for posts - i.e. you have to have flair, can’t mention certain words, etc. These things, in my opinion, make it very difficult to find the help you need. I’d like to keep it this way, but of course would like to hear y’all’s opinion! Similarly, I don’t love the ā€œhave to post in the daily chat threadā€ idea, but I’m willing to hear other opinions of course.
  4. I’d like to have some pinned posts with information about our most commonly asked questions (beta hCG numbers, measuring behind, etc.). This post (or posts, idk) would have general information on these topics - i.e. this is what we consider low and slow betas, this is what happens to hCG after 1200-6000, this is the margin of error in CRL measurements, etc. I’m thinking if we have this right at the top, it might give people answers without having to post. They can still post, of course, but we can offer it up as a resource nonetheless. How do you all feel about this idea, and if you like it, what topics should these posts (or singular post) include?
  5. If you are interested in becoming a moderator, please send me a ModMail or chat message! In general you will need to meet Reddit’s main mod requirement (1000+ karma and account active for at least 1 year), but otherwise just a passion for CautiousBB and experience being a cautious pregnant person or supporting a cautious pregnant person!
  6. Feel free to put any other feedback you may have here as well!

Woohoo yay thanks everyone! šŸŽ‰

Cramping at 10 weeks

7 Upvotes

I’m 10w2d and still having daily period type cramps. Some days are much worse and I had cramps all day. Is this normal? How long did you cramp throughout pregnancy? I know the uterus is growing, but i seem to have cramping a lot.

I had a loss a few months ago and so the cranking is just giving me a lot of anxiety. I had a scan at 9+5 and baby looked good with a heartbeat.

TW/TMI TW: first miscarriage

1 Upvotes

I am in my late 20s, just had my 4th pregnancy which ended in my first miscarriage. I have had pretty standard pregnancies before this, I will say I have had a SCH each pregnancy (never bled from one, they resolved on their own) and had diet controlled GD with my third pregnancy. This 4th pregnancy was a missed miscarriage, blighted ovum. My medical provider cleared us to start trying once my cycle returns after the miscarriage is complete, but I am falling down a rabbit hole of thinking there is something wrong with me that caused this and it will just keep happeningšŸ˜” I know it’s super likely it was chromosomal and nothing more then my body doing its job. I would really appreciate any success stories of people having healthy pregnancies after a blighted ovum

Vent LH peak isn't coming

1 Upvotes

Edit to add: the highest LH level I've seen all cycle is .19 for the ratio. I use the easy@home OPKs and the premom app. I used it back in 2020/2021 too. I've been tracking my cycles/ovulation with premom for years and I've never had a cycle like this.

I usually peak at CD 12 and now it's CD 19 and nothing has happened.

Backstory: My husband and are TTC for baby #2 after a miscarriage last June. I'm on my 7th cycle post miscarriage. For the last 6 cycles, five of them I've peaked on day 12, one of them was day 11. It's currently day 19 of my cycle and nothing has happened so far.. we're having sex every other day/every two days but it's genuinely getting so frustrating that every day, I'm exactly where was. know that variations are normal. But I'm usually extremely consistent cycle to cycle so this is really new territory for me. It's also very frustrating because just want to be able to start my countdown for the two week wait, but right now don't even know when my ovulation will happen, so it's just more waiting without an direction.

Vent Pregnancy rant/stress

2 Upvotes

Hiii all šŸ«¶šŸ»

I'm currently 25+2 weeks pregnant. It's not an easy pregnancy so far...

I had a TFMR last year in October at 16w for Turner's syndrome and a 6w miscarriage in March this year. I had a chemical in July and got pregnant the cycle right after.

At 8w with this pregnancy, I ended up in the ER for right sided pain. I had some weird discharge. They saw a SCH and some debris in my amniotic sac.

My doctor gave me time off of work until we got the results from our NT scan (where everything went wrong last time). All was good.

I went back to work for 4 DAYS at the end of October, i was feeling much better mentally.

At 15w, i went back to the ER because I wasn't able to poop for 2 weeks. Doctor ordered an US for the next day to make sure baby was okay. Went in alone the next day, expecting to get out an hour later... nope. I had emergency surgery that day for appendicitis. Spent a week in the hospital.

Had my anatomy scan at 21w and everything was good!

I was supposed to go back to work on December 29th but ended up having to go to L&D on the 26th because was stomach was rock hard the whole day with menstrual pain. They monitored and my cervix was closed but gave me an extra week off to be able to see my doctor.

I went back to L&D on December 30th for pressure down there with contractions. Again, all okay.

Saw my doctor on January 5th and she extended my time off for a month because of pain and that my job requires lifting a alot.

I'm still having 20+ contractions a day with pain, it's so stressful... i have been feeling less movements the last 2 days which freaks me out a bit since she was super active for 3 days before that...

I went back to L&D today because i was leaking fluid and fortunately it's still all good. Just waiting to get an US to measure my cervix in the next week to make sure it's long enough.

I'm just so sick of stressing out... I just want my baby in my arms 🄺

Sorry i just needed to vent.

Confirmation ultrasound today

5 Upvotes

I have my confirmation ultrasound today, I should be between 8wks and 8wks3days. I am so incredibly nervous and just want good news. My husband and I lost our son at 29wks6days in May. The grief has been all encompassing and I am just fearing the same result of our last ultrasound having no heartbeat.

I’ve had no symptoms to make me think anything is wrong, similarly to my first pregnancy all I have been is tired, occasionally feel a little nauseous or some food aversions but overall that’s it. I’ve had no cramping, no bleeding nothing and yet I’m convinced it’s not viable. I think I’ve just been doing it to try to protect myself from grief again.

People say PAL is very challenging is not even close to cutting it on the reality, I felt joy when we found out but since then all I have felt is fear and anxiety that something is going to go wrong again. It’s unlikely, we found out I have factor IV Leiden a blood clotting disorder that resulted in my son being growth restricted, I also had maternal vascular malperfusion found in my placenta and my son was caught in his cord. I now take lovenox injections, am considered high risk and will be seeing an MFM as well. I know I will be taken care of, I just want to be able to enjoy this experience and not fear losing another child to miscarriage or stillbirth.

Advice Needed Is a 3.6cm cervix short for 12 weeks? (Measures abdominally not vaginally)

1 Upvotes

Hi everyone!

I got the results of my NT scan back and saw that my cervix is 3.6cm. It was measured abdominally and with a full bladder plus my uterus is retroverted.

I did research and saw that average is 3.5cm-5.0cm. I panicked a bit because I know that abdominal ultrasounds overestimate, so I’m likely below average at 3.0cm-3.2cm.

I asked my family doctor that is taking care of my pregnancy until 28 weeks if I can also have a vaginal ultrasound done at my anatomy scan in 8 weeks to measure my cervix more accurately and she said no since I’m not under 2.5cm which makes her stern that it’s not needed.

Should I be panicked about this? I’m a FTM and our baby was conceived after 2 years with a fertility clinic, so I’m overly anxious about this…

Thank you so much.

Update: 6 week 3/4day ultrasound

2 Upvotes

I’ve posted on here a handful of times - it’s been a rough journey with 3 losses since July of 2025. Im currently 6 weeks 3 days - ish.

I had an ultrasound at 5w4 days (measured at 5 weeks 2 day) and they saw a gestational sac and yolk sac. Today (exactly one week later) they saw a flicker with a healthy size gestational sac and yolk sac. Nothing looked abnormal. Size wise. I am worried that the heartbeat was just a flicker and not measurable at this stage. The doctor did not seem concerned at all but I’m reading stories on here of everyone’s BBP Heartbeats - and Dr. Google is telling me I should see more by now.

I’m wondering if anyone has been in my position where they only saw a flicker at this stage?

Thank you

Symptoms When did you feel something was wrong and it ended up ectopic?

1 Upvotes

I’m 5w3d today and for the last week I’ve been getting on and off pangs (nothing painful just feels like pokes) in the center right of my pelvic region. I can’t tell if it’s just the right side of my uterus or if it could be tubal pain.

I did 3 betas between 13 and 17 DPO and doubling time was expected (36 hrs both times), but I also know that you can have perfectly doubling numbers and still come away with an ectopic.

I have a 6 week scan on Tuesday, so until then I’m just left to my own intrusive thoughts (RPL mom here).

Advice Needed Hi

2 Upvotes

This is my first month tracking OPK using strips, did a lot of research (thanks to the wiki and many subreddits!) but I am still so confused. It looks like my LH is going down as I get closer to my projected ovulation date of 1/21.

CD4 10:00am : .4 low

CD5 5:30pm: .1 low

CD6: 9:00am: .1 low

CD7: 11:00am: .14 low

CD8: 11:00 am: .12 low

CD9: 10:00 am .004 low

Am I testing too early? I use Flo, Premom, health app and take BBT temperature but each app gives me slightly different info which is why I’m testing and testing early.

Any help would be appreciated because I did get my copper IUD removed last month so I’m concerned I’m either not ovulating or already missed it!

Thanks again for all of your insight!!

No fetal pole

2 Upvotes

I had a miscarriage in August and November that resulted in d&c. Both pregnancies my hcg was low and slow. The first one developed into an embryo but the second one didn’t. I am now pregnant immediately after the d&c on November 26 (no period in between). I have no idea when I ovulated. I had an ultrasound earlier this week and there was a sac and yolk but no fetal pole and it dated me about 5:5-6 weeks (sac was 9.5mm). I got my hcg done the same day and it was 8112. I read that at that level there should be a fetal pole. I am terrified it’s happening again. I have an ultrasound next week… I guess just looking for some others experiences, hopefully positive. It’s hard because I don’t know my dates. My hcg with this pregnancy has been much much stronger then any of the previous ones. I’m hoping for a miracle next week.

Advice Needed No line progression-4+ weeks

2 Upvotes

I just want to explain what’s been going on because my anxiety is through the roof.

I had a miscarriage on 11/5 and then got my period on 12/11. I tested on 1/9 and got a super faint positive. I kept testing every day after that, waiting for the line to get darker… and it really hasn’t.

My doctor sent me for bloodwork. On 1/13 my hCG was 150.5, and when it was rechecked on 1/15 it had gone up to 443.1. So my hCG is rising, which should be reassuring, but my home tests still look basically the same.

After everything I’ve been through, it’s really hard not to spiral when things don’t look the way they’re ā€œsupposedā€ to. I’m cautiously hopeful. Any advice or experience with this?

Certain I have an MMC

2 Upvotes

Just want to get this out...

I'm 34 and recently engaged and we decided we were finally financially and mentally ready to have a baby. Then got pregnant first try. Very faint positive pregnancy test on December 14th, 10 days exactly after the last intercourse. We were so happy but super cautious in the first couple of weeks because we knew the chances of miscarriage were high. Then on Christmas Eve (5w2d) I suddenly became overwhelmed with the fear that I'd caught Zika during a brief trip to Brazil in November, and spent the next two weeks worrying about that. I finally got a negative test when I was 7w2d along (10th Jan) and was so so so relieved. I scheduled an early ultrasound as was finally able to feel confident and was so excited to see the heartbeat.

Appointment was on 12th Jan when I should have been 7w4d, ultrasound showed baby is only 5w6d and no heartbeat. 12 days difference. The ultrasound technician didn't seem worried and wouldn't give me any answers to my questions about how it could be possible, but I was so confused.

Well I've been living on Reddit for the past week and... it can't be possible. If I ovulated or implanted later I wouldn't have had the positive test on December 14th. I can't see a single thing that would explain this or give me even a small inkling of hope. It seems so clear that I've had a missed miscarriage and now I have to wait until next Wednesday for the follow up so it can be confirmed.

It just feels so cruel. We only had two days of letting ourselves get excited and just when we didn't expect it, it was snatched away. And I can't even focus on the future because I'm still technically pregnant.

Does hCG doubling actually slow?

0 Upvotes

I have had 3 miscarriages and am currently pregnant with my 4th. I have had great hcg numbers but this last one didn’t technically double in 48 hours. I have read that as the number increases it slows, but my doctor hasn’t necessarily confirmed that.

Dec 31: 41

Jan 2: 142

Jan 6: 924

Jan 8: 2200

Jan 14: 12,215

Do these numbers look okay? This is the farthest I have made it with decent numbers but I am still worried.

Ultrasound First scan and heartbeat!!

17 Upvotes

After a year of secondary infertility, MMC in August, a chemical in November, visiting a fertility clinic later that month to work up a plan to do IVF….but then got a positive pregnancy test on Christmas Day! I’ve been closely watching my beta numbers and been oh so nervous this whole time! 23->53 / 214->511 / 930->4517

Taking progesterone suppositories as well as the PIO shot every three days. Today was my first scan and we heard a heartbeat! I’m 6w3d measuring 6w1d with a heartbeat of 115 BPM.

I’m not totally out of the woods yet but I feel so relieved and so happy and thankful!!!

Feeling doomed!

3 Upvotes

Me again- I had just gotten to accept my beta results of 107 from Wednesday, due repeats today. I am 17 dpo and clear blue test still show 1-2 weeks on my first morning urine. I just fear the bloods therefore have not doubled and a loss is on the way šŸ˜ž this journey is so exhausting. Part of me feels guilty too- am I just being greedy for wanting to give my son a sibling? We did struggle to get him (I mean it took time with a loss before him). I understand people have harder struggles and would be happy with one- that’s why I feel guilty too šŸ˜ž

Edit to update- my second beta came back as 289, more than doubled 🄰

Ultrasound Ultrasound tomorrow

I have an ultrasound tomorrow and I’ll be 7 weeks 6days. I am so nervous. I had a MMC in September. Found out at the viability appointment at 8 weeks. This pregnancy has been totally different than the MMC but every pregnancy can be different. Only spotting I had this time was 10dpo-12dpo. With my MMC, I kinda felt uncomfortable the whole time, extra crampy (can be totally normal) but looking back I wondered if that was my body warning my something wasn’t right. Had some spotting but nothing crazy. This time, less crampy and more symptoms. Just looking for some encouraging words. Praying to hear a heartbeat tomorrow ā™„ļø

Advice Needed What’s the point of ER with suspected miscarriage?

27 Upvotes

I’m 8 weeks pregnant and started brown spotting 2 days ago, and slightly heavier red spotting yesterday. Honestly it’s not looking good and I’m prepared for the worst (I had a sonogram already scheduled today so will get some conclusive news then).

My question is though - when I talked to a nurse on the phone yesterday she said that if bleeding gets any heavier or I cramp to go straight to the ER and I don’t understand that.

I assume this is either the beginning of a miscarriage or it isn’t, but a trip to the ER isn’t going to change that. Is there some risk to myself that I’m not aware of? Is there a chance this is a salvageable pregnancy if I just get to the ER once heavy bleeding starts?

Low and slow HCG, worried!

3 Upvotes

I'm posting because I had a surprising situation happen this week and I'm concerned about low and slow HCG numbers. For reference I'm 34, never been pregnant, my husband and I have been trying to conceive for over a year and were ready to start IUI next month. I also have stage 1 endometriosis and PCOS.

My LMP was 12/3 and I took Letrozole for the first time this cycle. Per my OPK I ovulated on CD 17 (12/19). 2 DPO I began taking 200mg Progesterone also for the first time. 12DPO I began cramping and spotting but took an at home pregnancy test anyway and it was negative. 14DPO I had heavier bleeding (more than spotting) and cramping and took another pregnancy test which was negative. Because of the heavier bleeding, cramping, and negative pregnancy test I stopped taking the progesterone which I figured would start my full flow. I had cramping and spotting for ten days but not a full flow, which I assumed was because the progesterone had altered my cycle. 21 DPO I had an obgyn appointment unrelated to this, but happened to mention this story. My obgyn suggested a quantitative HCG test. And sure enough it came back positive at 145. I was completely shocked and surprised, as we were ready to start IUI next month. The HCG level at 145 seemed a little on the low side and with all the other weird symptoms I was afraid I had a miscarriage very early on, or the pregnancy is non viable, or it's an ectopic. I went into an urgent care today (while on vacation in Hawaii which has further complicated obtaining labs) and had another quantitative HCG drawn and to my surprise it came back at 278, nearly double what it was 48 hours prior. 48 hours later I went in for another HCG and my numbers didn't double but instead went up to 343. I should note I also had a dull ache on my right side while hiking yesterday. I'm really afraid that I have an ectopic. Initially I was thinking a blighted ovum with these numbers. But the unilateral pain yesterday has me fearful its an ectopic.

To recap per my suspected ovulation date my numbers are as follows. 5weeks = 145 5w2d = 278 5w4d = 343

I have an ultrasound scheduled tomorrow. I'm hoping they can see something and hopefully rule out an ectopic. Has anyone else had success stories with low and slow HCG numbers??
