Why you might not hear babys heartbeat You might not be able to hear a babys heartbeat at your first ultrasound. Most commonly, this is because its too early in the pregnancy. This doesnt necessarily mean theres a problem. Your doctor may recommend you schedule another ultrasound 1 to 2 weeks later.

What happens if there is no heartbeat on ultrasound?

The scan picture shows a pregnancy sac with a baby (or fetus or embryo) inside, but there is no heartbeat and the pregnancy looks smaller than it should be at this stage. You may have had little or no sign that anything was wrong and you may still feel pregnant. You might still have a positive pregnancy test.

Will you miscarry if baby has no heartbeat?

To conclusively diagnose a loss, a doctor must perform an ultrasound to check for a heartbeat. The heartbeat does not develop until 6.5–7 weeks of gestation, so the absence of a heartbeat before this time does not indicate a loss.

Can an ultrasound with no heartbeat be wrong?

Miscarriages are predicted by doctors when a womans embryo or gestational sac seems too small, and when an ultrasound shows no fetal heartbeat. (In the cases included in the study, doctors had detected a gestational sac in the uterus, ruling out the risk of an ectopic pregnancy.)
