Which birth control pill should i get?

Hey y’all! So I’ve had sex a little less than a month ago for the first time. Im 17 years old & not ready for pregnancy so I’m currently studying which birth control pill should I get on. I’ve been doing some research & i’ve found that there are progestin only pills and combination pills. I think i want to go on the progestin only pills (mini pills) because i’ve seen some of the cons & side effects of the combination pill that i’m a bit skeptical about. But, which y’all think i should go on & which is better & why?
