You can definitely still get pregnant. After you have a baby you're very fertile.

I had my baby last year 6/3 and didn't get a period til close to end of sept and I didn't BF. And I wasn't on BC since I couldn't start the pill until I had a period. The dr told me it can sometimes take up to 3 months for a normal cycle to come back. And I've heard people say it takes longer to get a cycle when baby is BF
