Egg cell and becoming pregnant
A woman can carry a child in the uterus. This is because an egg, of which one is released each month from the ovaries (ovulation), is fertilized by a sperm cell. Eventually, this fertilized egg cell nestles in the uterine wall.

What happens when an egg cell doesn't get fertilized?
An egg lives for about 24 hours. If it is not fertilized in the fallopian tube, it arrives dead in the uterus.
The uterus does have a wall, consisting of blood, water and food, built up (endometrium) in which a possible fertilized egg can nestle. If the egg is not fertilized, this wall is rejected, this is called menstruation or period.

Menstruation cycle
A woman is pregnant about every 4 weeks. So menstruation happens in a cycle, starting on the first day of menstruation. On about the 14th day, menstruation takes place.
Every cycle takes around 30 days.

Menopause
Because all egg cells are present when you are born, they can ''get out of date'' and are no longer usable. This happens around age 45-50. This means a woman is no longer fertile and doesn't menstruate.
