Hi, Welcome to HealthcareMagic Forum.
You are having Hormonal
Imbalance which could be due to PCOS
. You may want to get yourself examined by a Gynecologist to rule out the exact cause. You should be exercising regularly for 30 to 40 minutes and eat healthy nutritious balanced diet which should include fresh fruits and green leafy vegetables. You will require Hormonal drugs to make your Periods regular along with changes in your lifestyle. Avoid high calorie foods.
Wish you Good Health, Take Care.
