Hello and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I would suggest to consult the gynecologist first and undergo USG scan and ovarian follicle study to find any pathology. Drugs like clomiphene, citrate, metformin, progesterone pill will help in conceiving. Clomiphene citrate help in inducing ovulation and increasing fertility. Metformin decrease insulin resistance and maintain glucose homeostasis. Progesterone support implantation and pregnancy. You should take above medicine after proper evaluation. For losing weight avoid high fat diet, fast food, take heavy breakfast, adequate lunch and light dinner. Do regular exercise like running and skipping for 45 to 60 minutes in the morning daily followed by yoga. Take more fresh fruits and green leafy vegetables and drink plenty of water. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Sagar
