What's a good birth control to get on after having a baby

Jessica
My little boy is now 3 months old and I am looking into a different birth control than the pill. I am on the pill for almost 2 months but I don't like it. I would like something different so I don't have to take a pill every day. I have been looking into the IUDs they now have out or the one that goes in your arm. Anyone have an problems with them. I have an apt on feb 12th to talk to my doctor about it but I wanna know from people that have been on those types of birth control
