Contraceptives After Birth?

Liz
I'm a FTM (17 weeks + 3 days) and I'm wondering what people use for birth control after their babies are born if you're breastfeeding. I keep forgetting to ask my midwife and I don't see her again until next week. I thought I read you couldn't take oral contraceptives if you're breastfeeding, so what else are you supposed to do? A coworker told me I'd be "fertile-myrtle" after he's born (her exact words) 😂😂
