Constant red bleeding at 4weeks post Parton

Katie • 27 years old, married
I've just called my health care provider and left a message (in a meeting) about this but wanted to ask if anyone else still had bright red lochia 4 weeks post delivery? 
It's not really slowed much since about 4 days post and i keep reading it should have at least gone lighter or changed colour by now. 
Is this cause for concern or did anyone else have this and it ended normally? 
I had post partum hemmorhage immediately after birth as my placenta wouldn't come away and so I'm wondering if this has caused a problem. Also had stitches from tearing and episiotomy
