Birth control?

I am currently 16 and pregnant, I was on the pill but didn't take it properly. I got put on the implant well pregnant and got it taken out for the harsh side effects or could have been pregnancy. Anyways, I have time, but I'm trying to figure out what to use for my next birth control once I give birth. I hate being on hormonal birth control, so I'm left with the copper IUD, but I heard so many horror stories. I rather not have the IUD, I don't like people in my vagina from past sexual assault. I plan to breastfeed, anyone have any birth control recommendations? Or advice? This pregnancy was not planned and we are waiting until we are older to even think about having another baby.
