At 7+3 Sophies was 108-110, if I remember correctly, and I freaked the HELL out. I had a thread on here. There has never been a thing wrong with her at all, and she's worn my fitbit charge hr (lol) and her heart seems to beat pretty vigorously these days. I actually got told it was a bit slow and there was a chance things weren't going well, so it was a dreadful time of worry between then and my first try of a doppler at 15 weeks.
She never had a heart rate as high as Thomas did during my pregnancy, hers sat around 135bpm from 15 weeks, his was more like 160bpm.
