Advice 🤦🏾‍♀️!

So basically I’m in this relationship with my boyfriend & we’ve been dating for a month & I’m ready to have sex but it’s to early in the relationship. And we’re only 14 so I feel like we’re young . But I WANT to have sex with him . And I’m scared of getting pregnant even tho we WILL use protection but condoms are 98% effective & I don’t wanna tell my mom can I get on birth control because I wanna have sex at 14 .
