Birth control... help!

Miranda • 22 years old, first time mom of a baby girl born 12/8/18

Hey girls so I’m 10weeks pp and starting a new birth control tomorrow, I’m currently on the mini pill but I’m terrible at taking it on time, either implant or iud since I’m breastfeeding. Any recommendations? Im leaning more toward the implant because I’m terrified of putting something into my uterus and it somehow messing up my ability to conceive. What is your opinion? Help!
