Hi, Your irregular period could be due to hormonal imbalance, PCOD, thyroid dysfunction, and endometriosis. I would suggest you to consult a gynecologist and undergo reproductive and thyroid hormone analysis, USG scan, ovarian follicle study for better management. You can use provera for 5 to 6 months in second half of period to regularise period. Metformin can be useful for ovarian dysfunction. Drugs like Clomiphene citrate and ova care can be used to increase fertility. Take theses medication under advise of a gynecologist. Avoid stress, take healthy diet, drink plenty of water, do regular exercise and reduce your weight if you are obese. Hope this may help you. Contact further if follow up needed. Best regards, Dr. Sagar
