How do I ask my parents about birth control???

Kati

I’m in my first serious relationship and I’m 17. We’ve recently started having sex. We have been dating for almost 10 months. We always make sure to use a condom and to be extra cautious. But I really want to take the extra step and use birth control but I don’t know how to talk to my mom about it. I’m worried she won’t let me be alone with my boyfriend ever again if she found out I’ve already started having sex. Any tips or advice to help me out???
