Menstruation Or Periods

Basically menstruation or in general period is a process in which vaginal bleeding is a part of a woman's monthly cycle.

Why does Menstruation Occurs?

The body of a female prepares herself for pregnancy every month. But if you are not ready for pregnancy then your womb or uterus sheds away its lining. This menstrual blood that sheds away is not just blood but it is partly tissue and partly blood exit out from inside the uterus through the vagina. This menstruation cycle or period usually lasts for 3 to 5 days while it starts occurring from the age of 11 to 14 years and ends until menopause is attained at the age of 51.

Scanty Periods

Women usually get their period every 21 to 35 days and are consistent in their flow and days.

While your menstrual flow usually occurs for two to seven days in number.
