hope it will help you dear..!
Explanation:
A period happens because of changes in hormones in the body. Hormones are chemical messengers. The ovaries release the female hormones estrogen and progesterone . These hormones cause the lining of the uterus (or womb) to build up. Once the egg leaves your ovary, it travels through one of your fallopian tubes toward your uterus. If pregnancy doesn't happen, your body doesn't need the thick lining in your uterus. Your lining breaks down, and the blood, nutrients, and tissue flow out of your body through your vagina. Voilà, it's your period!A period releases the tissue that grew to support a possible pregnancy. It happens after each menstrual cycle in which a pregnancy doesn't occur—i.e. when an egg hasn't been fertilized and/or attached itself to the uterine wall. The uterus then sheds the lining which had grown to receive a fertilized egg.
EXTRA'S :-
a girl can get pregnant before she gets her first period. Getting pregnant is related to ovulation. Because a girl can ovulate before having her first period, it is possible to become pregnant if she has sex.
