Thoughts on the patch?

So

I'm 17 turning 18 this October and I'm thinking about starting my sexual life with my boyfriend, but I'm kind of irregular and I dont want to take the pill because all the things it causes like getting fat (bc im already fat lol) or nausea. Also im underage so I cant get the DIU hahah so i thought about the patch and i've been reading about it and i think its the best for me but I wanna know if any of you tried it before If yes how was your experience? And I want to know if you would recommend it for me at my age
