Having a period is part of the reproductive cycle. It basically works like this: your ovaries release an egg every month. A hormone called progesterone begins to prepare your uterus for the fertilization and implantation of that egg into the lining of the uterus...aka pregnancy. The levels of another hormone, estrogen, go up too. When a pregnancy doesn't occur, the hormones progesterone and estrogen go back down again. This causes the lining in your uterus to need to regenerate itself in preparation for the next time your ovaries release an egg. This is when you have your period. This entire cycle takes about a month. Your actual period is the last step before the entire process starts all over again.

I know this probably seems confusing so the short and sweet answer to your question is that your uterus needs to get rid of the egg released by your ovaries every month and your period is the way it does that.

Being a woman, I understand that having a period is disgusting, messy, smelly, painful and just plain not fun, but it is a necessary part of the reproductive cycle.
