OB/GYN Appt PP?

When/why did you return to your OB after having a baby?
I left my doctor for a midwife/birth center during my pregnancy, but before getting pregnant I think I was going annually to renew my BC pills prescription... I know I need to wait until I'm done breastfeeding to get back on the pill, is there any reason why I'd need to go back to my OB before that? 
*Sorry I totally didn't clarify 😝 I'm 5 months pp I've had my 2 and 6 week appointments but my midwives don't go any further than that... I was asking when I'd return for a regular, non pregnancy related appointment!
