Oh i'm so sorry to see this post

With a blighted ovum (or a missed miscarriage), the placenta part of conception continues to develop and make your body think it is supporting a baby...and therefore you hcg keeps climbing as it normally would and you have all pregnancy symptoms...however the baby stops developing. It seems like a very cruel trick!

My first miscarriage was one of these...so my heart goes out to you in this uncertainty.
For me i went for a scan at 9weeks (because i thought i was having twins i was showing that much!)and they picked it up. No fetal pole, no HB, and a very small yolk sack. Was measuring like 5weeks or something like that. She told me that it could either be a blighted ovum or my dates were wrong. I knew that my dates weren't wrong (especially by 4 weeks!!). I had hcg checked and it had started to drop by that point but it was still in the 100's of thousands. I didn't miscarry for another three weeks until it had started to drop right off. I did have another scan two weeks (i think) after and it had gotten even smaller.

I will be praying that maybe your dates are wrong....but in case they arent' I just wanted to explain what is happening. And once again i'm so very sorry to hear xx
