TMI......Difference between Lochia and first postpartum period?

Jade • Amalia Aya Durand.... 18.08.19 💕😍💕

LO is 3 weeks old today. My bleeding after birth stopped 3/4 days ago and I've had no cramping in about 10 days.

Today I started having a very light pink bleed with a slight brownish colour to it. No cramping, no pain but a light flow of bleeding/discharge. I've read Lochia is bright red blood but this doesn't seem like a period to me.

Anybody with a little more postpartum experience than me know what this is?
