They bleed from their mid-section for days (varies from woman to woman and month) every month. This only happens when a woman is not pregnant because before the start of the menstrual cycle (bleeding), an egg is released through the fallopian tubes from the ovaries every month to prepare for pregnancy and the egg embeddes on the side of the uterus. If sperm does not reach the uterus then the uterus lining that has built up for the egg will shed resulting in a period and bleeding.

A period is when once a month a girl bleeds from her vagina. A vagina is the hole where babies come out of her body between her legs. If a girl does not have a period, she may be pregnant. The bleeding of her period means her uterous is shedding the lining and she is not pregnant. (The Uterous is the round organ at the top of the vagina that holds a baby) The blood and the lining stays in her vagina to cradle the egg and nourish the baby. Not having a period does not mean that you are always pregnant. Not having a period can mean that you are tired, not eating right, exercising too much and so on. Or they might be a medical problem that needs looking into.

Oh dear. Almost all women go through something called Menstruation, or they," get their period" Each month, a womans body prepares to get pregnant and nourish( feed) the baby that's going to grow inside her. The body prepares by having a lining that is rich in blood, grow in the uterus, that's where the baby grows, not in her stomach ! This lining waits until an egg is fertilized by a sperm and decends through the fallopian tubes to the uterus.When it gets there, it attaches itself to the wall of the uterus and thats where it stays and grows until it is born. If the egg is not fertilized then the lining is shed( comes off) and comes out of a womans vagina as blood.
This generally happens once a month and lasts about 4 to 7 days.
Hope this helps,
Johanna

Periods are menstrual cycles. Menstrual cycles range from ever 28-31 days. It has to do with pregnancy by this, at a certain time of our cycles, we release an egg (this is called ovulation) once the egg is released and it is joined by a sperm, it implants itself in the uterine wall. Once a month, our bodies does sort of like a "run down check" to where the body will check to see if a fertilized egg is implanted. If one is not, that's when the menstrual flow begins. If there is one found...guess what, no menstrual flow and that is the first real sign of pregnancy..... UMMMM, I think that I just gave a run down of the birds and bees?

It's a normal cycle. They know when it is due because it always comes at that time.
When they miss one, they could likely be pregnant because their body does not release the fluids necessary for sustaining the baby's life that month.
