Ack family controversy!

Sophia
Okay, so my mom is a Christian and here view on sex before marriage is like, " Nuhhhhh gurlll you better not." Recently she said that I should get on birth control because I'm gonna have "fun" with my baby anyway. I use to have a job, I'm 17 and she isn't gonna pay for my birth control. Do you guys know if a planned parenthood is able to work down the price? I know it'll come down based on insurance and yearly income but I don't have the money to pay for anything like that.
