Postpartum bleeding

3 weeks pp and still bleeding? It stopped for a few days and all of a sudden came back? It also feels a little sore down there, I know they say give it 6 or more weeks to fully heal but I feel like I should feel better down there at this stage, is it normal to still bleed and feel a little sore or should I go get checked out? The midwife did check me a few days after birth and said everything was fine?
