TMI! What and why?

So it is now 31 days since I first started bleeding with my miscarriage, and I am still getting this when I wipe. I think this looks like old blood, but I never had this before the miscarriage, and it has been accompanied with CONSTANT cervical throbbing/pulsing, which has been lasting for days. I also never had this pulsing before the miscarriage.

Does anyone relate to any of the above? Or may know what is happening?
