Audrey • Mommy of a beautiful 💖 a handsome 💙💙

I just had a baby a month ago so I'm not trying to get pregnant right now. me and my significant other want to start trying again in about 6 months to a year, what birth control should I use if I want to try again in 6 months to a year? what birth control can I get pregnant right away if I stop using it?

also what birth control can I take now and have sex immediately
