Options for BC!

I'm not on any form of birth control because I haven't needed to be but have been thinking about it a lot more recently. I was leaning towards the pill bc it seems to be the most convenient for me but I know there's still so many different choices for the pill! I was always wondering about side effects because vomiting and gaining weight make me nervous about taking it! Also my skin is relatively clear and I don't want taking it to give me bad/uncontrollable acne! Opinions/advice??
