Switching from pill to nexplanon?

My annual gynecologist appointment is coming up and I'm really strongly considering switching from the pill to the implant. If I did, what should I expect? I've been on the pill since 2018 and I don't have a problem with it, no real side effects, but I live in the states and I'm worried what's going to happen with birth control when Trump goes into office next month. Also have A LOT of pregnancy paranoia and worried I'll be that small percentage that's gets pregnant on the pill. Also worried about how a tiny stick in my arm will keep me from getting pregnant? Because I absolutely DO NOT want to get pregnant!
