Heartbeat

Holly

I went in last thursday for an ultrasound. I was 6w 5d. and they found a heart beat at 114. I went back in today after some bleeding after intercourse.(7w 1 d) And he did an exam. My cervix was still closed and it seemed to be old blood in there. I also had another ultrasound and the heartbeat was only 85.... the tech said they tend to fluctuate a lot between 6-10 weeks. Anyone have the heartbeat drop and still have a healthy pregnancy?
