Hi i?m 27 year old and trying to conceive. I had 30 day cycle, 11 days long period. So my gynae prescribed me duphaston from 1st day of period till 21st day. So I started taking it from 28th jan i.e my first day of period. But since then I did?t got my periods. I went again to doctor, she did my ultrasound and hcg test both were negative so she gave me primolut n to start periods for 5 days. But it?s my 12th day today, I did?t got my periods. Is it duphaston that?s delaying periods? It?s been two months now please help. There?s no cyst or any other problem.
