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? Everyone's trying to convince me that I'm having twins lol.
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!
