I just had my second scan (after them only being able to visualize the gestational sac on the first 10 days prior) and was able to see the yolk sac, fetal pole and heartbeat. Based on the ultrasound, I measured 6 weeks 5 days. However, the heartbeat was only 80 bpm. The tech showed me everything after she had taken her measurements but both my mom and boyfriend who were in the room said that she only took a reading for about 3 seconds right at the end. I could physically see it beating though and it was the most amazing thing. While I'm still trying to be positive, my OB (well technically the nurse) has freaked me out a little bit. She wants me to have a repeat ultrasound next week to make sure the heartbeat picks up (although she claimed not to be too concerned since its early) and cancelled my appointment today which was just to go over paperwork and take blood, I think. (This is the second time she has changed something on me and I'm starting to think she likes to make me worry.) Do you think this is really low or has anyone had any similar experiences? I keep reading things and have seen it go both ways, but in my heart I feel like everything is going to be okay although I need some reassurance while I wait yet another week.
