Simply
put: 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. This monthly process is called menstruation or a period.
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.
The actual flow of your period doesn’t feel like much when it’s happening. Chances are, you won’t even feel it coming out. When you actually start your period, you may feel some dampness in your private area — this may be caused by a few spots of blood on your underwear.
It shouldn’t! Menstrual odor happens when menstrual fluid comes in contact with air. When menstrual fluid is absorbed within the vagina, like through a tampon, it is not exposed to the air, so there shouldn’t be an odor. If you’re feeling worried, just be sure to change your pads and tampons frequently to help keep odor at bay.
Menstruation itself doesn’t hurt, but some girls and women get cramps or other symptoms during their periods that may be uncomfortable. This is typically due to the hormones your body releases during menstruation that cause the uterus to contract so it can shed it’s lining.
Yep! During your period, it’s important to keep yourself fresh and clean. They’re a simple way to stay feeling feminine and fresh. Always Incredibly Thin Liners and Always Extra Protection Liners are great choices for daily liners that help you feel dry, fresh and confident every day.
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.
We’re not sure what exactly causes cravings and other PMS symptoms, but it seems like hormones are involved. Some women really want foods like ice cream, chocolate, and potato chips when their period comes. Need something sweet? Reach for fruits instead. Want fatty, fried, or greasy foods? Choose healthier fatty foods like salmon, nuts, or avocado.
Your menstrual
cycle is counted from the first day of your period up to the first day of
your next period. 
The typical
menstrual cycle is 28 days long, but each woman is different. 
Also, a woman’s menstrual cycle length might be different from month to month.
