How Can Amenorrhea Be Treated?

Hi, I am 37 years old, and I did not get periods from last 2 months (my last period started on 15.06.2015) and after that i never had periods, when i met my gynic she advised me get the HB test and tyroid test which was absolutely normal and pregancy test was negative and ultra sound scanning report was normal. She advised me to take promolet tablets for 5 days (10 tablets) which was taken by me 15 days back, still I am waiting for my periods. Doctor please advise I have already examined by 2 gynics
