First time posting here and a little nervous. So I recently went through fertility treatment as have struggled to get pregnant but had success in September! I have had scans 6 and 8 weeks and all showed heart beat had another scan today at 10 weeks 3 days and baby is growing right on tracks with dates but heart rate is 143 bpm and was wondering if that was a little too low? As have seen others with 160-180 odd I think I’m just a natural worrier haha
