I had my 6 week u/s and the tech found 2 sacs both measuring about the same size. However, only one sac had a little bean with a strong heartbeat and on target. The other sac appeared black with no yolk or fetal pole. The tech did not seem optimistic and thinks it is a blighted ovum. I did get a call from the nurse asking me to repeat the u/s in a week without explanation so I am assuming they want to see if the sac #2 has either developed or has been absorbed. I am ecstatic about my little bean but can't help but hope that the other sac will develop. I am very nervous and thought that some of you may have some positive stories to share. I have read that it is possible it may just be measuring behind and can catch up. What do you think? Was the u/s too early?
