There doesn't seem to be a problem, but if your periods are regularly irregular I would advise you to visit a gynecologist so that you can be evaluated and undergo investigations such as ultrasound to find the underlying cause and have it treated accordingly. These steps may help with regularizing your periods: - Avoid fatty, oily, fried and junk food - Exercise regularly (minimum 30 minutes of cardio exercises everyday) - Destress yourself with practices such as yoga/meditation - Maintain a healthy body and diet (as per your current BMI you're mildly overweight) - Have vegetable juices - Include corn, beets, lettuce, drumsticks, and pumpkin seeds in your daily diet - Avoid smoking and alcohol if you have the habit
