Reasons : Reasons for a missed period besides pregnancy are stress, illness, poor diet, extreme exercise, weight loss, hormone imbalance such as with thyroid disorders or polycystic ovarian syndrome and even peri-menopause if you are older. If you continue to have missed or irregular periods, contact your doctor to discuss.

Hormonal imbalance: Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. If you miss more than two periods it would be time to see your doctor. If you do not wish to be pregnant, use contraception all the time. You may consider implanted contraceptive or an IUD.
