why do girls get thier periods?

Answer 1

The menstrual cycle enables the female body to prepare for the implantation of a fertilized egg. If fertilization does not occur during that particular cycle, then the lining of the uterus (the endometrium) is sloughed off and a period occurs, then the cycle begins all over again.

Answer 2

during our monthly cycle, blood builds up on the uterin walls; this is where the egg implants itself after it is released from our ovaries. If the egg is fertilized, a hormone is released that prevents the blood from sluthing off (washing away the egg). That's why you DONT (in most cases anyway) have a period while you're pregnant. But of course the reverse of this is, if the egg is NOT fertilized, no hormone is released, and the egg and blood are sluthed off, resulting in a woman having a period.

Answer 3

About Your Period



Throughout a woman’s lifetime, her menstrual cycle and her period can change due to changes in hormone levels as she ages.
Maybe you’ve been getting your period for some time, or maybe the experience is brand new to you. As you get older, you may find that your period seems different than it used to be. In all cases, it’s important to remember that every woman is different. Some women have shorter, lighter periods, while others have heavier, longer periods. Any of these scenarios are perfectly normal. And it’s also normal for a woman’s period to be different from month to month and to change over time.3, p. 381 E, F




The Basics

Menstruation is the shedding of the uterine lining through the vagina as a bloody discharge.3, p. 379 It is actually composed of cervical mucous, vaginal secretions, and tissue from the uterine lining.3, p. 381 D Here are a few general points regarding the range of experience that women have with their periods:

Most women do not need to change their daily activities or exercise routines when they have their periods.
* Most women lose only about 4 to 6 tablespoons of menstrual fluid each month.3, p. 381 D

* Periods can be light, moderate, or heavy.3, p. 382 A

* It’s perfectly normal to have a period that lasts anywhere from 3 to 7 days.3, p. 381 D

* A woman’s first period is known as menarche, and normally occurs between the ages of 10 and 17.3, p. 381 A

* From menarche, a woman gets her period roughly each month until she reaches menopause, which generally occurs in the late 40s or early 50s.3, p. 381 A

* Most women do not need to change their daily activities or exercise routines when they have their periods.

* Throughout a woman’s lifetime, her menstrual cycle and her period can change due to changes in hormone levels as she ages.3, p. 381 F

It’s important to make the distinction between a period and breakthrough bleeding. Breakthrough bleeding is a term that describes bleeding between periods.3, p. 385 A For some women, breakthrough bleeding is a normal and harmless part of ovulation. Some women on oral contraceptives may also experience breakthrough bleeding especially during the first few months of use. This is not typically associated with an underlying health problem, and usually goes away over time.3, p. 422 A But for some women, breakthrough bleeding between periods can be a sign of any of a number of reproductive system disorders, including vaginal tears, problems with the cervix, endometriosis, uterine fibroids, or reproductive disease.3, p. 385 B Talk to your health care professional if you’re concerned about breakthrough bleeding.
