When did your first postpartum period return?

Lissett

I’m 11 weeks PP, not breastfeeding just formula feeding but I still leak a little milk. My period hasn’t returned yet.. I’ve also been having slight pink discharge only when I wipe for about 2 days.. been crampy as well.. is my first postpartum period coming soon? When did yours start? I know everyone’s different, this is also my first baby
