There isn't sufficient information t give you a specific diagnosis. I would advise you to visit the gynecologist so that you can be examined and undergo investigations such as ultrasound, thyroid profile, etc. to find the underlying cause and have it treated accordingly. These following steps may help with regularizing the periods: - Avoid fatty, oily, fried and junk food - Exercise regularly (30-45mins/day) - Destress yourself with practices such as yoga/meditation/tai chi - Maintain a healthy body and diet (Maintain a healthy weight as per your BMI) - Have vegetable juices - Include corn, beets, lettuce, drumsticks, and pumpkin seeds in your daily diet - Avoid smoking and alcohol if you have the habits
