Dog bleeding

My dog had 8 puppies on jan. 27th. So the pups are now one week and one day old. Pups are fine, but my dog is still bleeding.. Like it drips when she walks, puddles when she is laying down, she shivers and barks sometimes, and has been having a lot of diarrhea. Is that normal with a nursing mother dog? I've never owned a dog before and wasn't aware she had been pregnant until a little bit before she gave birth.. Help please! She's around 2yo
