Low HCG. :( What does this mean?

post #1 of 21
Thread Starter 

I just got an email from my mw and she said that my thyroid looks fine but admitted that it's not her specialty so I should see what my PCP thinks.


But, she said that my HCG "was really low though - 135." :(


So this is why my HPTs have been taking so long to show up and darken up.


I found some comfort in this page. These paragraphs make me feel like there's some hope:


Caution must be used in making too much of hCG numbers. A normal pregnancy may have low hCG levels and result in a perfectly healthy baby. The results from an ultrasound after 5 - 6 weeks gestation are much more accurate than using hCG numbers.

By LMP, I should be 6 weeks on Friday, but I don't think I'm that far along because I know when I felt ovulation. We dtd on Christmas Day, so conception could have even been after Christmas if I O'd late (and that was my first cycle after the m/c, so it could have been whacky.)


This chart shows these ranges as "normal" ranges for HCG by gestational week:


  • 3 weeks LMP: 5 – 50 mIU/ml
  • 4 weeks LMP: 5 – 426 mIU/ml
  • 5 weeks LMP: 18 – 7,340 mIU/ml
  • 6 weeks LMP: 1,080 – 56,500 mIU/ml


According to that chart, I could be weeks (I calculated 5 wks, 4 days today) and still be in range.


Has anybody had "low" HCG and had a healthy pregnancy?

This is the first pregnancy where I've had betas done and they were on the high side, so I can't speak to having low and things being fine.  But it does seem from those ranges that your in the norm.  I have read that there is a huge range of normal, and that one level can't really tell you much.  What is more informative is how it increases, so you might want to do another 48 hours after the first.  That will give you a better idea.


have you checked out betabase?  awesome source of info  http://www.betabase.info/


I hope this is a perfect pregnancy for you.

Isn't it more about them doubling in a day or two rather than what they are at any given time? Mine have been through the roof both times which might explain why I was
sick, sick, sick for 9 months. If you are doubling but low early on, from my perspective that is an enviable position! I hope for you that's what it is and all it means is that you won't puke your guts out everyday!

My midwife doesn't sound hopeful and I just called the OB's office to try to get my progesterone # and she didn't sound hopeful.


If I go today to have blood drawn for the 48 hour HCG, it would probably come in tomorrow (my birthday) and I don't know if I want to ruin my birthday. Or, it might not come back until Monday and I'll just have to wait and wait. I'm a little concerned about an ectopic pregnancy because I know HCG is often low.


This sucks.

I'm so sorry.  :(  The doubling time is very important so hopefully that can give you more information.  There was one study that said that a single hcg level done at 16dpo was very predictive of pregnancy outcome but it's hard to extrapolate from later draws.  Here's the link to that info:




Of course, with any study or statistics there are never 100% guarantees and while people may say that low levels or levels not doubling every 24 hours is a sign of miscarriage, there are those who just have a slower rise.  Hoping that's you!  Are they considering doing an u/s to check on things?

I think HCG has to be over 1000 or 2000 before you should be able to see anything in a u/s, right?


I might try to back to the OB's office today for a blood draw to check HCG. I don't know if results would be in by tomorrow or Monday. I don't know if I really want to know. :(

Meta- I'm so sorry, I hope that you're just one of those woman who have low levels, but that 's just normal for you.  I think you're right about the levels being over at least 1000 (it might be higher) before it's visible on u/s.


the best way to know is another hcg.  could you have it done today and ask your mw not to tell you until monday?  


hugs :hug

I'm with kateaton - getting it done but having mw wait to tell you. also, I have a friend who had low levels early on and was really slow to rise but all turned out well in the end and she had a very healthy baby girl!

You're right about the u/s - I wasn't even thinking.  Hugs!

I'm sorry Meta. I hope everything is okay.

I'm a little worried about the possibility of an ectopic pregnancy. I've had a tiny bit of spotting and one of the signs, aside from light spotting, is a low and slow-rising HCG.


Maybe I should try to get an appointment with the OB's office today. I don't know what they'd do though since with an HCG level of around 135 (two days ago), they probably won't be able to see anything on a u/s whether it's in my uterus or in my tubes.


I've gone from holding onto hope that I'm just earlier along than I thought and hoping for a healthy baby to worrying about my own life. This pregnancy stuff is crazy.

Fingers crossed for you.  Will be checking for your update and hoping for the best.

Thanks for all of the well wishes. :grouphug


I had another blood draw this afternoon for HCG and will hopefully know by tomorrow afternoon. My progesterone from Tuesday is only 5.68!! That's horrible! I've read that low progesterone along with low HCG can be indicative of an ectopic. And I'm still bleeding. It's not heavy and I don't have any cramps or pain - it's more like CM with streaks of red blood - and not much of it.


My mw said she had two ectopics herself so I feel a little more confidant in her ability to see things through.


I guess we wait and see what HCG is and go from there....

I forgot to add this funny part:


I had the blood draw and then was sitting in the waiting room with Ds waiting for the plebotomist to come out with my progesterone numbers from Tuesday when guess who walks out of a different exam room?? My sister!! So she was there trying to get answers for some weird stuff she's had going on and I was there with my weird stuff but neither of us had told the other because we didn't want to worry one another. :lol So then we both explained ourselves and I feel like "Why don't I just tell her everything all the time??" It's nice to have someone here IRL (besides clueless DH) to talk to about all of this. She's leaving for Florida with my Mom on Monday until early April, but I can always call her.


I think it was a sign - or meant to be - or something. The Universe must've known we both needed some support and set things up that way. The Universe never ceases to amaze me.

Metasequoia - Thats so great! I'm so glad things happened that way! Sending loads of positive energy your way!
post #17 of 21

Glad you and your sister ran into each other and bonded that way!

Very sorry the news doesn't sound reassuring about this pregnancy, but still hoping the best for you and waiting to hear how things go. I'm glad you have a mw that you can trust and rely on in this situation, no matter what it ends up being.

post #18 of 21

Very sorry for your loss, Metasequoia, and more for it happening on your birthday. It's never good, but that's just not fair. Healing thoughts your way, even as I try to stop myself from "worst first" thinking right now also.

goingonfour - hope everything is ok?

post #20 of 21

Thanks, Cricketschirpin!

Still don't feel the least bit pg, but am grouchy as a wounded bear! Oh, I know this is bad, but if I weren't pg, I would have dearly loved to have had a beer or 3 tonight! Not going to wish for the chance to have any, any time soon, but the house is a pit and I just flat didn't care. Then decided we had to have some shelves, then spent too much time measuring and trying to figure out how to make it happen today, then got overwhelmed and gave up, then realized, it's not about the shelves. Felt a little crampy, asked DH to run get some cheapo tests, and he gladly accepted the chance to Get Out, and well... apparently everything's fine so far. So it's really just... me.


It doesn't help that DH is stressed about finances and still reeling from the loss of his father, my mother was congratulatory but hasn't called since I told her the news a week ago, and my social life is on the rocks. Bad combination.


Hoping to have a brighter outlook tomorrow. And hope all is well with you, too. :)
