I had my first U/S on 10/28/11 and was 6w1d pregnant, but the U/S measured 5w1d with a normal yolk sac, but no baby. My Dr. was not concerned but scheduled a follow-up U/S in 2 weeks, which I just had on Thursday, 11/10/11. I was 8w0d, but only measuring 6w1d, same yolk sac and still no baby. I knew something was wrong. My dr. came in and told me that she was concerned b/c at first I was only 7 days behind, but now I am 13 days behind, and still no baby. She told me I most likely had a blighted ovum, and did not expect a good outcome as she attempted to console me. She said she was not going to jump to anything just yet, and ordered another U/S in one week (this Wed. 11/16/11) and we would go from there. She did also order a total HCG & progesterone to get a better picture of what was going on. I mentioned to her, that from my understanding, a blighted ovum will not present with a yolk sac, but she said that is not true and blighted ovums can in fact contain a yolk sac. So my question is, 1) Could this be a blighted ovum and 2) How much chance do I have of this pregnancy being viable? I have already accepted that it is most likely a doomed pregnancy, but I am still holding out hope. I also have pregnancy symptoms, some which are new like nausea. Some have decreased such as breast tenderness and need to urinate frequently. Please someone help me figure this out either way; I am so deperessed and can't focus on anything else. Oh, I also have a healthy 3 year old daughter (had a perfect pregnancy with her). Thank you in adavance for
