I see all of these horror stories of heavier periods when they return postpartum, but has anyone had them get lighter?

I’m 11 months pp and still breastfeeding/pumping. I’ve had intermittent spotting through the week this week… could this be my first period? Or something else? It doesn’t seem like enough to be a period…

We’re hoping to start TTC again in a few months as we’re older, so I also hope it isn’t a sign something is wrong!
