Hello, Welcome to Health Care Magic. I read carefully your query and I understand your concern. The irregular period is due to bilateral PCOS (polycystic ovarian syndrome).The cause of this syndrome you have been diagnosed is your overweight. Overweight cause resistance insulin, this cause excess insulin in blood causing high androgen hormonal level and decrease of progesterone hormone level, for this reason your doctor had prescribed to you glycomet (metformin) and gestofit(dydrogesteron) synthetic progesterone and the other drug that you didn’t remember probably was Provera (medroxyprogesteron acetate),another synthetic form of progesterone it is taken 5-10 days at month day 16-21of the menstrual cycle, but you should go again to the doctor before you taken the pills. I recommend you to choose a healthy lifestyle and lose weight, choosing a healthy diet for reducing the weight and the insulin blood level its recommendable high-fiber and low-sugar carbohydrate foods e.g. fresh fruits, non starchy fresh vegetables ,whole grain; you should avoid sweetened juice, starchy vegetables( potato, corn, peas),white floor foods: breads, pasta etc, sugar drinks and foods (cakes ,cookies etc),snacks as Doritos. You should do minimally 30 minutes of brisk walking every day. To reach the goal of lose weight I recommend you to go to a dietitian and frequent a gym advised by a professional instructor. Loosing weigh you can prevent PCOS and other disease that have high risk to develop in the next future by your overweight problem. Hope this answers your question.
