when can you feel a baby heartbeat
At six weeks, your baby's heart beats at about 100 to 120 beats per minute, speeding up to about 160 to 180 beats per minute at 10 weeks, then slowing to 130 to160 beats per minute by the beginning of the second trimester, where it will remain for the rest of your pregnancy. 1  1. 2  2. 3  3. 4  4.
