Every pregnancy is, of course, unique in its development, and each woman’s prenatal care will vary.

Some doctors recommend that unnecessary exposure to ultrasound (especially near the baby’s head) be avoided until 18 weeks.

In a routine and healthy pregnancy, it isn’t uncommon to have only one or two ultrasounds for the duration of the pregnancy.

A transvaginal ultrasound (an internal ultrasound) can detect a heartbeat around 6 weeks of pregnancy.

However, it isn’t uncommon to be unable to detect a heartbeat via ultrasound until closer to 7 or 8 weeks.

While many mothers are able to see the heartbeat around 6 weeks, some maternity care providers prefer to wait until 7.5 weeks or more.

By waiting until 7-8 weeks, it is less likely that a dating error could lead to not detecting the heartbeat in a healthy pregnancy.For these reasons, each woman is likely to see or hear her baby’s heartbeat at different stages in her pregnancy.When you see your baby’s heartbeat could depend on your maternity care provider’s typical prenatal care, your risk level in pregnancy, and the accuracy of dates in your pregnancy. Some women will have early ultrasounds to confirm pregnancy, or to check the location of the pregnancy if there’s any concern (e.g. Some scans can detect a gestational sac around 4-5 weeks of pregnancy, but that’s still too early to detect a heartbeat.This type of dating is based on averages, as many women ovulate about 14 days after the start of their last period, and expect a new period 14 days after ovulation.However, the exact day of ovulation can vary from woman to woman and cycle to cycle.Find out more about week 6 of pregnancy in our informative pregnancy week by week series.
