Hi ladies.. can anyone shed some light on postpartum bleeding??

My son was born 26th July.. Bleeding slowed up by day 10 then started to get heavier like a period.. now 19 days pp bleeding still the same and have now also passed quite a big clot?? Only 1 for now but is this normal? Anyone else have something similar?

Must add not having any belly ache pains or feeling of dizziness
