8weeks pp and spotting?

Ashley • I'm 23. my son is 2 yrs old. And my bf is 24 We've been together for 8yrs in sept. Expecting our baby girl April 14 !!
So I'm 8 going on 9 weeks postpartum me and SO have only had Sex 3 times since June 1st. I had stopped bleeding around week 5 postpartum. I'm breastfeeding, we aren't using protection and I'm not on any birth control and I don't plan on it until I'm done breastfeeding. He just pulls out. No I'm not looking for a lecture. Well tonight I noticed a pink discharge/ light spotting. Could I already be having a period ? I noticed slight cramping yesterday also. Tia 💕 (birth was natural and uncomplicated, no stitches)
