Want birth control, need advice.

I’m 16 years old and I am currently sexually active, and I use condoms but want and need a little something extra to ensure that i’m staying completely safe. I was going to talk to my mom about it, but in a different way. I was planning on telling her about how i was raped 2 years ago by my ex (but more in depth), and tell her about for 2 years I have been scared to death about it and guys, etc. I want to tell her how my boyfriend now has never attempted to force me or convince me to do anything of that nature, and we only kiss. (I know that’s lying a bit, but she already doesn’t like the guy and my mom really isn’t very nice). But i chickened out just before I was about to tell her all of that. Now I don’t know if I should tell her or not and how. I’m being safe already, but what if the condom broke yknow?
