Back in May I lost a set of identical twins at almost 5 months :( We had a failed IUI cycle in July and first round of IVF in August. We transferred 2 blasts that were hatching o their own on day 5 and got a BFP on Labor Day. First beta 14dpo 291 16dpo 770 18dpo 1491 21dpo 2620 I started to have moderate OHSS right around the time of my 1st beta. I gained 10lbs of fluid and look 5 months pregnant. I am having such a hard time breathing. I went in yesterday and they did a sono and didn't see anything. I was just 5 wks yesterday and am still very full of fluid but I was VERY discouraged that they didn't see a sac yet. Especially since the Dr had been predicting twins all along. they have me going back on Thursday for another sono at which point i will be 5w3d but I am sooo nervous. I am scared out of my mind. I do NOT know how I will deal with bad news after all I have been through already. I also have some slight cramping at times and some pain in my stomach. I can't help but think the worst. My progesterone and estradiol #s were good as well as my beta according to Dr's office but somehow that didn't ease my mind at all. I am driving myself crazy here. This is going to be the longest wait ever!!! I keep toying with the idea of just going to the ER and see what they say, but I really hate hospitals!! Please keep me in your prayers for a good outcome.
