Period at 8 weeks postpartum?

Katie

I am exclusively breastfeeding, and even when she sleeps long stretches at night, I get up to pump, so I never go more than a few hours without emptying my breasts. I did just start on BC last week, but my midwife didn't say anything about it causing my period to return... Also,my period is pretty light, just light brown with a couple very small clots. Has anyone else experienced this so early while EBF?
