If you’ve experienced any vaginal bleeding or spotting, or have significant pain, an ultrasound might be performed to check on the viability and location of your pregnancy (e.g. Like many procedures and medications during pregnancy, large scale double-blind studies to prove the safety or risk of ultrasound are nearly impossible.For this reason, the FDA and ACOG recommend that only healthcare providers utilise ultrasound technology, and only as medically necessary.

One question many mothers have is when can they see their baby’s heartbeat on ultrasound.

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.

Unfortunately, if you’re around 8 weeks of pregnancy, and your dating is accurate, a lack of heartbeat usually indicates a miscarriage.

Having an early ultrasound often depends on your maternity care provider, your personal medical history, and how your current pregnancy seems to be progressing.

It’s important to know that pregnancy dating can be off by up to two weeks.

If, based on your last period, you’re 6 weeks along but you ovulated a few days late, it’s possible that the scan was just too early.If you haven’t had any signs of a miscarriage and are less than 8 weeks pregnant, it’s possible that you’ve simply had a scan too early.If this occurs, your maternity care provider might recommend coming back in a few days or a week, to check again.Pregnancy dating is only an estimate, and doing an ultrasound just a couple of days too early can mean unnecessary concern and worry about not seeing baby’s heartbeat.Early ultrasounds might be used routinely, or only when there are concerns.Find out more about week 6 of pregnancy in our informative pregnancy week by week series. A mother’s size, the position of her uterus, the location of baby, and the accuracy of dating can all affect when a heartbeat is seen on an ultrasound.
