Hello, There are various reasons behind irregular periods. What is your body weight? Are you overweight? Visit a gynecologist and get yourself examined to rule out the cause. You can visit my clinic International Fertility Centre located in New Delhi for further evaluation.

Periods are affected by several factors, like medicines, change in routine, stress, thyroid disorders. Single irregular period should not worry you. Keep a track of your dates for next couple of months. You will need investigations in case it recurs.

Irregular  period( early or late) is a sign of underlying  hormone imbalance  if it happens  on a regular  basis.
