Hello, i have done all tests thyroid, usg, everything seems normal but still my periods arent on time. Also tried taking deviry 10mg twice a day for 7 days as told by dr but no periods till now on 7th day. What to do? My periods have always been irregular. Im done with trying everything also im unmarried so tired of going here and there. Only thing i can say is my weight is 80kgs but inspite of that if i have taken medicine periods should come right??
