Dear Sana, Ovarian drilling is one of the methods to achieve egg release from the ovaries in cases of Polycystic ovarian syndrome (PCOS). Glucophage is metformin which helps control the raised levels of insulin in PCOS. Please continue taking them; it is a useful medicine. However, I feel Myo Inositol is a better choice which controls the increased levels of insulin as well as androgens. It has got better pregnancy success rate. Pregnacare and Folic acid are good vitamins which help healthy eggs and implantation of fertilized ovum. In PCOS, you should control your weight. Find out what is your BMI; you should keep it under 24. High protein, low carbohydrate and low fats is a good diet which should be supported by appropriate exercise. If with this treatment you do not conceive within 6 months, please report to Infertility specialist; you may have to go for Artificial Reproductory Technique. I hope this helps you.
