Birth Control while Breastfeeding?

Hey friends! So I’m about 8.5 weeks PP now. Obvi I wasn’t on birth control after last time I gave birth, because I got pregnant right away. I don’t need it right away, my fiancé has had a serious back injury for the last 7 months and it’s still unresolved, so we’re definitely not “active” ever or will be until he has surgery and recovers. BUT I’m wondering for when I do start birth control..those of you who breastfed, what was your birth control of choice, did it affect your supply, pros and cons?
