I last had my period in june on the 23rd and in the end of june, beginning of july i had got a yeast infection. Then the whole month of july i had no period. So in august i took 2 HPT and they both came out negative. I went to the doctor and took another pregnancy test, and it came out negative too. Then i went back to the doctor to check out why i havent gotten my period, and to take a 4th pregnancy test which came out negative. Then my doctor prescribed me pills to take for 7 days in order for my period to cone down. the day after my last pill my period finally came for august, and came in september on the 13th of both months. It is now october and i recently had another yeast infection in the beginning of the month, and the doctor prescribed me 1 pill to cure the infection. It is now the 14th of october and i have not gotten my period yet. Can anyone help me please. I need some answers on what might be the problem.
