"WebMar 15, 2024 · A normal heart rate for a fetus can range from 110 to 160 beats per minute (BPM). Very early in pregnancy, it is typically around 110 BPM. Fetal heart rate may speed up to 140 to 170 BPM around the ninth week and slow to around 110 to 160 BPM thereafter. Fetal heart rate can provide lots of information about your baby’s health during pregnancy. " - Deceleration in fetal heart rate
