I hope it is ok to post here. I had a transvaginal ultrasound done last week at 7 weeks. I measured at 5 and half weeks and there was no baby or heartbeat. The ultrasound I had done was less than 5 minutes and I was left hanging and crying in the waiting room for an hour. I decided to get this week's ultrasound with the OB I had seen previously and after a through ultrasound, I measure 6 and half weeks but still no baby or heart beat. My appointment with my OB isnt until tomorrow but I just dont even know what to do right now. I had a missed miscarriage in October and had a d&c after I could clearly see the baby and no heartbeat but this time seems so different. I have bad morning sickness and what have you. Reading on the internet it seems like sometimes it takes a long time to see a baby and a heartbeat (not common but it happens). When do you throw in the towel? The tech mentioned this may be a blighted ovum and I also was wondering what anyone's experience with one might be. TIA.
