Hi! I was diagnosed with PCOS almost 3 years ago.. Last July I went to my OB-gyn and she prescribed me with provera to be taken twice a day for 10 days together with metformin 500mg twice a day.. after a week from the last dose of provera I had my period. On the first day of my period, I started taking evening primrose oil 1300mg once a day and continuously taking my metformin twice a day.. I had my regular menstruation for 3 months. That was August, September and October. But I haven't got my period for November.. I am almost 4 days delayed already.. Im having abdominal cramping every once in a while but other than that, I don't feel anything. Haven't checked with pregnancy test yet because I was thinking that this might be just related to stress because I was stressed during the first week of November.. what could this be?
