I have irregular periods problem since I had my first period. Sometimes I don't get periods for more than 2 months( I was getting regularly every month since Jan though). 3 months back I had done pelvic test which suggested no pcos, but gynac asked me to take normoz tablets which will help me with my irregular period prob and overweight issue. I have even done pregnancy test which came negative. Currently I have thyroid pills 75mg and 100 mg (alternate days change in mg) and normoz tablets twice a day.
