Early ultrasounds might be used routinely, or only when there are concerns.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.For these reasons, each woman is likely to see or hear her baby’s heartbeat at different stages in her 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.Your pregnancy is dated from the first day of your last menstrual cycle.For this reason, the FDA and ACOG recommend that only healthcare providers utilise ultrasound technology, and only as medically necessary.Ultrasounds use sound waves to produce a picture on a screen.The embryo’s heart begins to beat around 6 weeks of pregnancy – sometimes earlier, sometimes later.
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.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.
