What is an irregular period-?

A period or menstruation is the part of the menstrual cycle where the endometrium which is the lining of the uterus is shed in the form of blood through the vagina. The normal length of a woman’s menstrual cycle is 28 days but it may vary from individual to individual. Irregular periods are the one where this length increases to 35 days or more. Irregular periods also called oligomenorrhea can occur due to a change in the contraception method, any hormonal imbalance – like during menopause or enduring exercises. Treatment for irregular periods during puberty and menopause is not required but if the periods are irregular during the reproductive years then a strict medical advice is required.
