My mom won’t let me take birth control!! HELP!

Am

Recently I put out a comment about birth control and how to stay extremely active with my period. My period sucks guys.. I’m not saying it in the way we all mean, I mean it comes the WORST time possible and I mostly never get cramps but when I do get them I’m BEDRIDDEN and crying and i have a super high pain tolerance...

My mom was telling me that birth control increases my chance of cancer 1:5, might not be able to have kids, all this stuff... and yeah that all sucks.. but so does my period. I’m 16 so I am a minor and still gotta live under their roof/rules. And I don’t mind, my parents are great and I know she only wants what’s best for me... but she’s very dramatic and if I try to explain to her she says she “gets it” except back in “her day” if you will, food was different and I know processed foods play a huge role in body regulation. So she really doesn’t get it. I ALWAYS eat healthy.. I’m a health nut, but my period is still very hard sometimes. Sometimes it comes every 2 weeks!!! And sometimes in comes 3... but when it comes 2, it sucks....

What should I do??
