Birth control

I’m 14 & I want to be put on birth control without my parents knowing. It’s not for sex, it’s because of my painful periods. I would go to planned parenthood but it’s very far from my house and i live in a very small town where everybody knows everybody. I don’t want to get caught. I’ve looked into getting it shipped to my house but I need a social security number and I don’t know mine and I think my mom can find out that way.
