Nexplanon/Implant Question

I got Nexplanon (the bar) implanted into my arm last July, 2018. My fiancé and I are getting married and I want to get off of it so that I can give my body + my hormones a chance to return to their natural state (since I’ve been on some sort of birth control for 4-5 years, now).

Has anyone experienced problems after getting it removed? How fertile will I be after removal? We want a baby pretty quickly after marriage. Anything helps. Xx
