Postpartum

So I’m going to be calling my dr Monday but I’m 4 weeks postpartum and the bleeding was slowing down and then the last two days it’s been red and more so. Tonight I had a string of tissue hanging out and I pulled on it and it broke so I think some of it is still working it’s way out. Has anyone else had this issue ? It’s making my anxiety go crazy, I’ve been feeling pressure down there but no real pain since about 2-3 weeks
