I had my ultrasound yesterday baby measured 5.5cm, is 6 weeks & they said they heart rate is 115. Isn't that kinda low for a heart rate. Im nervous. I dont go in again for a while. Also pregestrone is 23 & beta was 17328
115 is typical for 6 weeks, I wouldn't stress!
I think heart rates can very widely in the first couple months. I was a little concerned for the opposite reason because ours at 9 wks was so fast (183) but was told that it was totally normal.
