Throughout pregnancy, your baby’s heart will continue to develop. Fetal heart rate starts at between 90 and 110 bpm during the first weeks of pregnancy. It increases and peaks at around weeks 9 to 10, between 140 and 170 bpm.
After then, during the second and third trimesters, a normal fetal heartbeat changes, and now ranges from 110 to 160 bpm. Keep in mind that your baby’s heartbeat may alter throughout your pregnancy and at each prenatal appointment.
Your doctor will monitor your baby’s heartbeat at every visit. He or she will check if it is too slow, too fast, or irregular. If so, there is a small chance that your baby may have a heart condition. If this is the case, a fetal echocardiogram may be scheduled to further assess your baby’s heart.
