When to start birth control?

Hey ladies! I'm 6 weeks post csection! This is baby number 2 and csection number 2! I was wondering when everyone decided to start taking birth control? I got my script for the pill and was wondering if I should start taking it right away or give my body some more recovery time before throwing off my hormones again? Thoughts please! :)
