I am married and my age is 27. My periods are always irregular from so many yrs. But this tym it has been two n half months and still periods r not coming. Discussed WD doctor and he advised me to take regestrone tablets for 5 days, completed course but no periods then again taken for next 10 days. I have completed my course for this tablets just yesterday but still not having periods. I'm feeling abnormal hair fall from last few months also. I have also taken pregnancy test but it is negative. please suggest me what should I do.
