Ok baby's first heart rate was 136 at 6 weeks. The next was 158 at 11 weeks. What would cause that big of a difference?…

thanks ladies! I appreciate that.

Mine was 108 at 6 weeks and 175 at 11 weeks!

Yeah mine has gone up and down from appt to appt, he said that is actually good and it's due to activity change. Just like our heartbeat isn't always the same. They want it in a range but doesn't have to always be the same!

it fluctuates

Ok. thanks! I didn't know as a ftm.

Baby growth and amount of activity could have a lot to do with heartbeat. It fluctuates a lot as baby gets bigger.
