Fetal Heart rate 7 weeks 2 days - 100BPM?

This is a completely normal heart rate for that gestational age. A normal heart beat at this gestational age is between 90-110 bpm. It will increase as the gestational age increases.

My son heart rate was 89 at 6 weeks and so many days and my doctor told me that it was a bit slow cause it was early days so I got it checked a week later and it was up in the 140 im now 23 weeks and everything is good just think positive good luck
