Is birth control 100%?

So, I've(19F) been on birth control since I was around 12 years old, so I have been taking them consistently everyday since, rarely missing any, and around the same time everyday. I have recently become sexually active, and I'm curious if birth control will stop me from conceiving. We have been using protection when we go all the way, but everytime we try raw, it feels easier for me. Easier as in, easier insertion and feels better in general.

So, can birth control stop me from getting pregnant? That's pretty much it.
