What is a normal menstrual cycle?

The average age when a girl starts menstruating is between the age of 11 to 14 years of age. A normal menstrual cycle varies from 24 to 38 days approximately. Any change from the above parameters, at any age, is called abnormal uterine bleeding and needs to be investigated.

Any bleeding which occurs outside these parameters and is different from the normal cycle for a woman is considered abnormal e.g.

Irregular, heavy, or intermenstrual bleeding in young girls

Bleeding in between periods
Bleeding after sexual intercourse
Cycles shorter than 24 days and longer than 38 days approximately
Irregular menstruation cycles

There can be several causes for the abnormal bleeding.

It may be due to an ectopic pregnancy in which the pregnancy starts to grow in the fallopian tube and has not reached the uterus. This can be dangerous and needs to be diagnosed early so that it can be managed without surgery other causes

Other causes

In young girls, while the hormonal axis is maturing there may be abnormal patterns of bleeding
Disturbances in ovulation and can lead to infertility
