Birth Control

So, I've been sexually active for almost a year now, and I really want to get on the pill, but I'm terrified of the side effects. Its going to sound so ridiculous, but the weight gain worries me a lot (I've alway been insecure about my body), and the emotional effects freak me out as well, I've had some struggles with my mental health before (last year), and I've recently been through some heavy family drama.

Any advice? Any other method you think might be more accurate?

(I'm seventeen, if that makes a difference).

Thanks!!
