6 weeks postpartum and light pink spotting?

Katelyn🧿 • im literally just a girl 🙂‍↔️• Mom💙💙🩷🩷🩷•

I noticed it on my panties, like a very small dot amount, I go pee and wipe and it's faintly there, put a pantyliner on and nothing since.

Postpartum bleeding ended around 2-3 weeks ago.. Any idea what this can be?
