Hello doctor. I am 24 year old girl. Unmarried. I have irregular menstrual cycle. I consulted a doctor and in usg my ovarian stroma waa found to be thick bt there was no cyst. All hormones were normal and doc said you have mild pcod. I took ocp (diane35) for 3 months till august and then my period was normal in sep and oct. But then from nov to jan I did not had period. In feb. I had periods like for 2 3 days and the amount of blood was very less. And then in march I did not have periods. My stomach is very tight and I look like a pregnant lady now. What could be the reason for that? What steps should I take now?
