This is for a friend of mine. She is pregnant, blood tests are good, in sonography heart beat was detected with 6 weeks pregnancy but the sac/embryo/foetus was not visible. What could be the reason? What does this indicate?

A. Hello my dear parent! It might be visible after a couple of weeks when the test is repeated. So for any concern, it is better to check with the gynaecologist for further guidance. Clarify your concerns and follow the doctors advice. Good luck and take care.
