Light pink spotting? 11m PP

I noticed a spec of blood on my toilet paper this evening. When I wiped again, there was a bit more (very small amounts by all means). I have not had my period return yet, breastfeeding my son & 11m PP but I did start weaning this week (only dropped 1 nursing session during the day). I have no period symptoms, no cramps. I’m curious if this may be the beginning of my first PP period?
