What does bilateral early diastolic notch mean?

Q: My wife has a 6th month of pregnancy. She recently had an ultrasound scan and the report is normal except it talks about the Bilateral early diastolic notch. Could you tell me about the this term.

A:It shows that blood supply to the baby is less. In these cases, If you will not take proper rest it can increase. If you have any history of blood pressure or swelling over feet you should be careful, and visit your doctor regularly.
