Welcome to the Preeclampsia Foundation

Yay Angie...I hope that heartbeat sent you a little sigh of relief!

I was waiting till we saw the embryo/heartbeat to say for sure because my RE said there was still a possibility of identicals when we saw just one sac last week, but today confirmed one sac, one yolk sac, one embryo, and one beating heart! :)

Mine doubled quickly in the beginning & then stalled for a few days. All turned out perfectly & obviously I only had one. Try to stay calm until your ultrasound. Can't wait to hear all about it!

Mine was taken at 5 weeks and then three days after and was suuper high. Only one :)

I had very high betas early on - right at the top of the normal range - but turned out to be just a singleton (thankfully given the early PE I had!). Try not to read too much into this until you get the scan.

Good luck

So, my 11 dpo beta number was great, 35.
My 17 dpo is...startling, 1469. --A doubling time of 27.45 hours.
(Both done at the same lab.)

The beta base website tells me that the median for twins is 500-something, and for triplets is 800-something. (!!!) But then there were 175 people with singletons with betas in this range, too.

I only had one mature follicle/egg the day before I triggered, but lots of little guys (like 10 mm and under-that's typical for me since I have PCOS.)

I'm a little worried about the possibility of a molar pregnancy too, but it seems like the odds of multiples are a lot more likely than the odds of a molar.

Luckily, I have an ultrasound Monday just to see the sac (or sacs.)

I'd appreciate any insight on this!
