Hello dear Understand your concern Femilon should be given in the PCOS to regularize the period. It support the cycle and suppress the cyst of ovary. It should be taken for few months with some gap in each month. Basically metformin is given to induce the period. But You have no period since 6 months, you required other treatment of PCOS with consulting the gynecologist: Metformin: for maintain glucose homeostasis and weight, induce ovulation Spironolactone and fulatamide: diuretic action and also induce ovulation Clomiphene citrate to induce ovulation and maintain fertility If not responds to medical treatment surgery like ovarian dreeling can be used Diet: take small frequent meal rather large meal Avoid fatty/spicy/salty foods Avoid excessive sweets Start regular exercise for 45-60 minutes in the morning Hope this may help you Best regards Dr. Sagar
