How does your period work?
there are 2 overies that each carry 200 eggs i think but each
month they take turns releasing an egg. their are a lining of
nutrients and when the eggs are released it goes all the way around
the uteris where if you have a baby it will grow in there, and if
the egg doesn`t meet the sperm ( a mans fluid fromhis private area)
it will scrape all the nutrients of andit willcomeout your vagina!!
itdoesn`t hurt!!!!!!!!!!! good luck!!!
