When did pp period return ?

I had my baby October 3rd (C-section). I went to my 6 week pp visit November 7th and got cleared. Last week I was feeling cramping thinking my period was going to start and never did & got some pink spotting for a day and it all cleared. Now I’m not feeling anything and feel pretty good just watery discharge. I’m not breastfeeding. When did everybody get there periods back ?
