A period is when a woman’s body releases tissue it no longer needs. This tissue comes from the uterus, which is where a baby (fetus) can develop in the female body. Every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. If the egg doesn’t get fertilized, that lining is released from the body as blood through the vagina.

So when a girl has her period, her body is just getting rid of a small amount of blood and some unneeded tissue. It is a natural, normal body process for all females as they become women and mature physically.
Starting to have periods is part of growing up for girls. Periods usually start to occur around the same time as other changes happen to the body, such as starting to develop breasts or to grow pubic hair. The average age to start periods is 13 but it is normal to start at any time between the ages of 9 and 15. A small number of girls may start before or after this. Periods continue until the menopause which is usually around the age of 50 years.
What happens during a period?
For several days each month there is blood loss from the vagina. The amount of blood loss varies from period to period, and from woman to woman. Some women have a dark scanty loss, some have a heavier loss which is a brighter red. Sometimes clots are passed, especially if the loss is heavy. Sometimes there are small flaky fragments in with the menstrual blood. A normal amount of blood loss during each period is between 20 and 60 ml. (This is about 4 to 12 teaspoonfuls.) Bleeding can last up to eight days but five days is the average. The bleeding is usually heaviest on the first two days. Some pain in the lower tummy (abdomen) – period pain – is common and normal.
The female hormones (oestrogen and progesterone) have other effects which you may notice apart from causing periods. For example, the texture of the mucus in your vagina changes at different times of your cycle. Your vagina tends to be drier, and the mucus thicker, in the first half of your cycle. Shortly after ovulation, when progesterone levels rise, the vaginal mucus becomes thinner, more watery and slippery. It becomes thicker again towards your next period as the progesterone level falls.
Progesterone may also cause water retention in various parts of your body. Your breasts may become slightly bigger or tender and your tummy (abdomen) may swell a little before a period. You may feel irritable before a period, which may be due to the hormone changes. To have such symptoms before a period is normal. Sometimes the symptoms prior to periods can be more severe. This is then called premenstrual syndrome or premenstrual tension
When will I stop having my period for good?
Women get periods until menopause, which is when menstruation and the ability to have children stops. In most women, it usually happens in their late 40sor early 50s. But menopause can happen earlier or later. Some women may stop menstruation by the time they’re 35 years old, and others may not stop until their late 50s.
How much blood do I lose during my period?
Most girls lose about 1/4 cup of menstrual fluid during their periods (mostly in the first few days). Not to worry, though — your body makes up for it.
In general, if you have a change from your usual pattern that lasts for several periods, it may be abnormal. You should see a doctor if this occurs.
