Period ?

I'm 8 weeks postpartum from having my baby. I'm curious to when my period starts back up. I'm very nervous because I had sex with out protection and no birth control at like 5 of 6 postpartum. When I had sex he pulled out but I'm still very nervous. I haven't been back to the doctor yet to get checked after having my baby I need to make an appointment soon. So ladies when did your period come after having your baby?
