Contraception help!!

I’m due to get my implant removed, and don’t think i’m going to get another put in. It stopped my periods for the first couple of years then very irregular periods until now, and i always felt like i was pregnant even though it wasn’t really possible (lol). Looking for advice as i’m unsure what to do now whether to go on the pill or just track it from my periods without any contraception. Thoughts? x
