When a girl goes through puberty one of the changes that occurs is that she will begin to have periods. This is the female body’s way of preparing to reproduce A woman’s reproductive system works on a 28 day cycle This cycle is known as the menstrual cycle The menstrual cycle consists of a number of stages

Day 1 – 7 The menstruation cycle starts with the first day of a woman’s period. This is the name given to the time of the month when the lining of the uterus comes away and exits through the vagina as blood.

Days 7 - 13 Day 7 - 13 Around day 7 the blood flow stops. The lining of the uterus begins to build up again. At this time an egg starts to mature in one of the ovaries

(The middle of the cycle) Day 14 (The middle of the cycle) On the 14th day which is the middle of the cycle, an egg is released by an ovary into the oviduct.

Day 14 - 17 The egg can last up to 3 days after it is released from the ovary. During this time the egg travels down the oviduct and into the uterus hoping to be fertilised.

Day 18 - 28 If the egg is not fertilised then the lining of the uterus begins to break down.

The cycle starts over again... Day 1 – 7 The cycle starts over again expelling the lining of the uterus and the egg. Remember this is known as a period or menstruation.

Now try to put the stages in order for yourself…
