Birth Control?? Help!

My boyfriend and I want to be extra careful when it comes to having sex, so we always use a condom. However, I’d like to get on birth control to be more safe and to give him more pleasure. The problem is that I am AWFUL at remembering to take pills so I’d have to get an alternative (like a shot or something) and my parents don’t want me having sex so I need a way to get on birth control without them freaking out or, if possible, finding out at all.

I know that the best thing to do is to probably talk with them about it, but my dad is super duper overprotective, and would probably murder my boyfriend if he found out.

SOOOO I need advice on how I can get on birth control without my parents knowing. Help!
