I had my 16 week appointment this am, which went mostly well. I've gained two pounds, blood pressure perfect etc. OB says I look great and pregnancy agrees with me lol. I told her I've been feeling movement and she didn't believe me until it took her about 10 minutes to find my baby's HB. As she was searching for the HB she kept laughing saying that she can hear and feel the baby moving, then she said, "I didn't believe you but baby keeps pushing back on the Doppler". While searchung she explained how baby's HB and mine sound different (mine has a pause and babys doesn't). When she finally got baby's HB (124bpm) it was beating the exact same as mine, faster but the same pause. She said its most likely nothing to worry about but if at my 20 week appointment it's doing the same I have to go for a fetal endocardiogram at 24 weeks to make sure baby's heart is ok. So I am very happy that I have an active baby but can't help but worry about baby's heart

Has anyone had experience with this at all?
