Not Sure If Menses

I'm 8 weeks postpartum and 2 weeks ago I had some very light bleeding which stop in 1 or 2 days. I thought it might be my period but just 2 days ago I had very light bleeding again which only stain half panty liner, and it's like 2nd day almost nothing and 3rd day very light again. By now the lochia should be over so is this menses? But its very very little unlike before. I'm exclusively pumping btw.
