If you are past seven weeks pregnant, seeing no heartbeat may be a sign of miscarriage. But there are many exceptions to the heartbeat by seven weeks rule. Youve likely heard of people who were certain they had miscarried or were not pregnant, and then went on to have a normal pregnancy.

What do doctors do if your baby has no heartbeat?

When the babys heartbeat does not show on the scan, the doctor may take blood to test for levels of progesterone (which are usually ten times higher during pregnancy). Coupled with a second scan that does not identify a heartbeat and blood results with low progesterone levels, the doctor will book a D&C.
