birth control after delivery?

Al

I've gotten pregnant on the pill twice now. otho tri cyclen lo and one that started with an M and was nicked name the mini pill because I was breastfeeding😅 and I had the implanon for 3 years and bleed for a whole year straight, and then had to get part of my muscle in my arm removed because it fused to the muscles, and I've thought about trying the IUD, but ive had horrible luck with implanted things I'm not sure if I should get it or not. what are you girls getting, and why.
