So I had an ultrasound done at 9weeks 1day and the babies heart rate was 184bpm. I went to my dr today and I'm 10 weeks 2days and when she found the heartbeat on the Doppler she said it was 164bpm. That it was still high and everything looks great. I mentioned the difference from the ultrasound and she told me that when the baby is smaller the heart works harder and beats faster and as it's growing it tends to slow down some, that not to worry everything is looking really good. Has this happened to anyone else? It is really normal? This is our rainbow baby so I'm super nervous and anything that looks odd to me I freak out about lol
