Dear Doctors, This question is for my wife. She has PCOS and after going through treatment she conceived on 1st april. Now she is 8 weeks pregnant. But in only three weeks we had 3 USG. First it was at 5 weeks. To confirm pregnancy .Then one week later for I.e 6 weeks for heartbeat. And now yesterday on 8th week 6 days. For Cardiac Activity .As she found brown spotting a week ago. Which was not there after that single day. But my concern is all USGs were performed internal. And I was not allowed to listen heartbeat. Is this normal to have 3 scans in such short time? And internal scans at 8 weeks? She is heavy weighted 96 kgs.
