I had protected sex on 13 march and I got my periods on 19 march. Now periods are delayed. I did pelvis usg and reports said that you have bilateral polycystic ovarian changes. Doctor asked me to do blood test like glucose, s.tsh, s.prolactin. I had regestrone tablets twice a day for three days coz I wanted my periods to come. I did not had any sex after last periods. I did upt too on the 8th day of missed period and it is negative. How and when will I get my periods? Please say.
