HCG Doubling Times

Hi Everyone - I'm onto my fourth pregnancy in 12 months and was wondering if anyone knows the rule on the HCG doubling time debate. I was feeling so positive after my first beta came back strong, only to be told by the clinic nurse yesterday that, in her exact words "wasn't looking good" because my numbers hadn't doubled in the 48 hours. They were 204 on Thursday at 14dpo and 331 yesterday at 16dpo - everything I read on the net says anything from 48-72 hours is normal and have worked out my numbers would have definitely doubled by the 72 hours and have gone up 62% in the 48 hours. Now I'm sitting here stressing until I have to re-test on Monday but just thought I'd ask if anyone had any experience with this themselves. I don't know who/what to believe!

Supposedly it's 48-72 hours. I've heard of them not doubling in that time and everything working out though.

:hug:

Thanks Schonell - well that makes me feel a little better as mine would definitely have doubled by the 72 hours, my doubling time was put at 68 hours and that's if it didn't continue to rise over the next 24 hours to take me to the 72. Urgh, I hate this, so much, I just want to be normal! :rolleyes:

Hopefully your bloods on Monday come back with amazing results :)

FX you have a H&H pregnancy and baby :)

If you google betabase there is a website with this name where real people load their beta HCG levels. I would include the link but not sure I am allowed to. There are lots of differences between people and I found the site invaluable during the early days of my pregnancies.

What times of the day did you get your BT on the Thursday and Saturday?

I can't say that I'm an expert....but the numbers look pretty good to me!

I've heard the 48 to 72 too and like Maruschke says, if you did BTs at different times of the day that can have a big impact on numbers.

Will have everything crossed for you that your results tomorrow are brilliant.

Hi Girls - thanks for all your votes of confidence :hug: Maruschke they were pretty much taken at the same time, Thursday morning was taken about 8.30 am and Saturday's were about 8.15 am. Guess I'll just have to wait and see what happens tomorrow, will keep you posted xx

Alison I know my FS is comfortable if they double in 72. Please try and relax I know it's hard but your mind is powerful and if your mind starts to think something is wrong it effects your body.
Goodluck for tomorrow :)

Those numbers look fine :)

The day AF was due I had a hcg of 18, which everyone was undoubtedly concerned with. My numbers also didn't double within 48 hours, but here I am 26 weeks pregnant with an active boy on the way!!!

Good luck

Hi Joeve - thanks so much, I am hoping i just got a cranky nurse yesterday - I'm going to ask a different one and see what she says and say something about them being too negative if she was wrong!! I know you can't believe everything you read on the internet but everything says 48-72 and Sunshine11 thanks for the tip I'm googling that site and it is really informative.

Just to add to what I said earlier hun, I have seen plenty of different HCG levels all over the shop on the forums, with the pg progressing well. I think your initial numbers look strong and that's really good, and even the second BT is looking pretty good to me too :) Stray stong hun and keep thinking positive for you and your lil embie. Will have everything crossed for you for tomorrow hun :crossfingers: xoxox

Alison, I totally get it, your fear that is. After 3 m/cs its normal to doubt your body's ability to carry a pregnancy and dwell on negative thoughts from others, but I can say that your numbers sound great to me.

Holding your hand through the scary first trimester :hug:

Alison, just wanted to wish you all the best for tomorrow. Try and stay positive though I've no doubt that's not easy. xx

Thank you all girls, you've made me feel a little more positive with your own positive stories and comments. Here's hoping for a good result tomorrow or I'll just crumble. I shall let you know how it goes. Love to you all xx

Hoping for great numbers today xoxo

Goodluck today hun xx

Fingers crossed for you, Alison.

Thinking of you Alison and keeping everything crossed for today :crossfingers:xoxoxoxo

Good luck today Alison x

I've been thinking of you today xxx

Hope all is well.

I've been thinking of you too. Got everything crossed for you for good news

Hi Girls - gosh you all make me feel so special, thank you :grouphug: Well the nurse today was much more positive and nicer, my levels have gone up from 331 to 612, so not quite doubled in 48 hours but she said as long as it either goes up 60% in 48 hours, or doubled in 72 hours then they're happy with that. Mine has gone up 85% so I have to be happy with that. My only concern now is stupid me forgot my suppository last night before bed - I think I was too stressed to remember anything, now I'm supposed to be on 3 I'm still getting into a routine on the 3rd, anyway my prog has dropped from 87 to 35. She said it will pick up again today but not to forget again as they like numbers to be at least 60 - has anyone any experience with this? Will they pick up pretty well straight away? Now I'm worried about those and my next test isnt until Thursday. Goodness does the worry ever end?? Thank you all for your support, it means A LOT!

Awesome have been stalking :)

Glad to hear your HCG results were good. Sorry to hear you are stressing about the progesterone. I dont know anything about that so I cant help there, but I do want to say just try and relax if you can. Easier said than done though, eh?

Glad your HCG came back great :) not sure about the progesterone sorry :hug:

So glad the levels are going up nicely hun!! It would be such a relief :) Big hugs and GL on Thursday hun xoxoxo

What a relief for you Alison - so pleased that you got a good result with your hcg. And a more positive nurse!!
Re: progesterone, my levels went up and down like a yo-yo for a while (I was on 2 x pessaries per night, forget the mg though). I also had constant light bleeding until about 8-9 weeks along. Ultimately the bleeding stopped and my progesterone stabilised. Hope your levels sort themselves out too - missing one shouldn't make a huge difference overall, I wouldn't have thought.
Keeping fingers and toes crossed for a super sticky bub for you xx

Yay. Fantastic news Alison. Can't help with the progesterone either unfortunately - I took tablets rather than pessaries, and was taking handfuls of things daily so no opportunity really to miss anything.

I'm so pleased for you. Hoping this bub is the stickiest of sticky babies.

Good to hear that Alison! xx
