Help Pleasee

So recently me and my boyfriend have been getting closer and closer to having sex. I’m always the one to stop things before they get to heated since he hates condoms and prefers for me to be on birth control. Currently I’m on the pill but I still stop it before things get to heated because I don’t want to take the risk and forget to take the pills. My school provides a range of different birth control methods such as the implant, The shot,Condoms, The IUD etc...

so I’ve been wondering which I should get?

My mind is In between the implant and IUD right now. Which do you guys prefer? What are some Side effects? And how will effect my menstruation cicle?
