Birth control for after pregnancy, please help!💕

I want a non hormonal birth control, because I plan to breast feed when my baby is born. I’ve trying to figure out what kind of birth control would work best for me. This is such a hard decision for me, I’ve been on the pill and that’s when I got pregnant, when I was pregnant I got put on the implant, because the pregnancy tests came back negative. The pill was way to hard to remember for me, and the implant was just not my favorite, I had for a month and it hurt every time I moved my arm I felt it, I couldn’t sleep on the side with the implant, I didn’t had any bruising, I didn’t like the side effects which could’ve been 100% pregnancy, but again it’s hormonal. Not only that when I told them I wanted it out, they told me no, I was starting to feel suicidal again, my mood swings where out of hand, I started to become an angry person I just wasn’t myself, getting out finally helped so so much. I am still very upset, they didn’t order a pregnancy test again, and they refused to take it out. I am very sensitive to hormonal changes, I really don’t want a hormonal birth control plus the breast feeding. The IUD scares the living shit out of me, I’ve heard so many horrible stories but also great. My doctor keeps pushing me for the copper IUD, again copper positioning is such a real thing, I’m scared to have it get out of place, I’m scared it’ll rip my uterus up, I want more kids, but I’m only 16, I am waiting until I’m older. The regular IUD scares me as well, I’m a very paranoid person when it comes to my health, I get extremely bad anxiety. If I have bad side effects I’m scared they’ll refuse to take it out like they did with the implant. What is your advice? What do you recommend?
