Scan anxiety

Jamie

I had an ultrasound last week Thursday (early due to previous loss) and was measured 5+6 with a heart rate of 124

Today I went for a follow up scan and I’m measuring 6+3 when I should be 6+5, which isn’t a huge margin but baby’s heart rate is down to 100

Has anyone had heart rate fluctuations without complications? Or could you tell me what your babe’s HR was at 6 weeks?
