Talk to Gynecologist on Harmonal Problem PCOS

Hi, so I have PCOS. The basic symptoms are extreme facial hair. Even if I wax the hair come next day. Tried lazer too. Did not work either. Hard Hair on upperlips, chin, side chin. Doctor prescribed Inofolic sachet with two other medicines. Now my problem is my periods were normal but after starting these sachet, last month my periods were 10 days late and this month I did not get periods at all. I am confused so I left the medicines. My weight is more than average too according to height and age. My height is 5. My weight is 69 kg. I am trying to lose weight but its kind of difficult. Should I continue these sachet? As i am not sure why they are making my periods irregular. The only thimg that was normal was my periods
