A young girl 16yrs old came with a complaint of absent periods. On USG she had multiple follicles in both ovaries. For which she was given ethinyl estradiol/ cyproterone acetate 35 mg for about 1yr. She doesn't menstruate without medicines. Her FSH LH levels are normal. TSH normal. Prolactin normal.

LFT'S & RFT'S normal. Size of the uterus is 62×31×17mm. Multiple follicles in both ovaries. Endometrial thickness is 1.3mm. Kindly give suggestions.
