I had an u/s at 6 weeks. Only a gestational sac, which was measuring 5 weeks. Waited 3 weeks and had a second u/s last Friday (should have been 9 weeks). Still only a sac that was only measuring 6 weeks. The doctor explained blighted ovum. My husband and I were disappointed, but weren't really surprised (i'd just had a feeling it wasn't a viable pregnancy) and we had made peace with it. I have a third u/s scheduled tomorrow. I was looking at it like a formality before we could talk about scheduling a D&C. Well, a nurse called me today and said that my levels (from blood drawn yesterday) were 22,000, so I definitely need to keep the appointment because they could see "something" with these levels. I was totally taken back. I just don't see how there is anyway there's really a thriving baby in there. In 3 weeks the sac (which never showed a yolk or a baby) only grew a "a week." I have lost all of my pregnancy symptoms. I had made peace with it and now the nurse has put it in my head that maybe there's hope.... I guess the point of her phone call was to make sure I showed up, since maybe people in my situation probably say "what's the point" and just skip it?? Thank goodness I only have to wait until tomorrow. I have spent the better part of the day searching, "miracles at 9 weeks."
