implant and drop experiences??

hi, so I'm almost 20 y/o and sexually active with my boyfriend. we're always super safe but we're wanting to not have to worry about condoms anymore, if ya catch my drift. so I am hoping to get on bc sometime soon or in the future. I am physically unable to swallow pills, so the pill form of bc isn't really an option. I'm not comfortable with the idea of the iud. I'm thinking the depo may be best for me but I've heard a lot of pros and cons. I was curious of experiences with the depo shot or implant?
