Debating to start birth control

Okay so I am 17 and a senior in high school, and I have sex very often with my bf; possibly once every week. Of course my parents do not know of this. We use protection every time but I was debating to get on birth control or not just so I feel even more safe that no pregnancy scare will occur. I need suggestions on what type of birth control to get on?

Getting birth control would have to be a secret too so I would need something to be able to hide from my parents
