A month

My first is was like 8 months. With my second well I didnt have one but I ended up pregnant 4 months after giving birth. I also had an emergency c section the first time and a repeat the second and this time it's a repeat too. I also nursed both my kids but due to getting pregnant when he was 4 months old I dried up pretty quickly.

My first I am not positive I didn’t have it at my 6 week check up and went right on birth control.

My second I got it the week before my 6 week postpartum appointment

With my first it was a year, never had a period after my second and he's nearly 2, I'm pregnant again too though.
