Birth control

So i was thinking about getting on birth control to help with acne etc. I feel like my doctor is low key trying to force it on me. But I don’t plan on having sex for a while. I’m trying this journey to celibacy until I meet the “one” and I was thinking about the implant for 4 years the only thing is i want kids really bad In the future and i don’t want this to ruin my chances of conceiving. Has anyone had trouble conceiving after getting off the implant? And did any weight gain occur? I have been on the depo shot and I did the pills also and I didn’t like either
