fleshy mass?

Paisley

I'm 9 weeks postpartum now and I started my birth control about 3 weeks ago, I haven't missed a day but on day 8 I started bleeding and I haven't stopped since, its like a period everyday it starts off heavy then just becomes spotting by night time however tonight I just passed this big blood clot thing, it had blood clot on both sides and was very fleshy in the middle and really dry feeling, I'm going to call my doctor in the morning but has this happened to anyone? I've already got an appointment for this whole bleeding thing though but I did hemorrage at 4 weeks postpartum, I had an emergency c section also but after the hemorrage this has totally freaked me out.
