The heart rate actually fluctuates throughout the pregnancy. The heart usually starts to beat about five weeks into the pregnancy at a rate of 75-80 beats per minute. It then quickens and reaches 165-185 around the 9th week. It then starts to decline, hitting about 150 around week 15 and maintaining around 145 until the fetus is full term.
I am 8 weeks pregnant and I had my first ultrasound yesterday. I was informed by my doctor that the baby is still an embryo and had a heartrate of 160 beats/min. I could see the heart beating on the ultrsound. add a comment
