Complications of still born puppy?

My dachshund just gave birth this week. She had a little girl pup about 8 am on the 22nd. After 5 hours of not giving birth to another I took her to a vet who after an exam told me she had two pups left but that one was probably not alive. He gave her a shot of some hormones to get labor kicked up again and within half an hour she had given birth to a second healthy pup. I noticed that she did not expel the afterbirth right away but I let her go on. That was about 3pm on the 22nd. She later got the after birth out around 7pm. That left only the deceased pup. Last night I noticed a foul odor in the air and noticed that she was having contractions again. I had to help but she finally got the deceased pup out. I noticed the cord had deteriorated to nothing and that the usual membrane that covers the pups was absent. I do not know if she expelled the afterbirth prior to this or not but she has to expel anything else. She is having an awful smelling discharge. I'm just wondering if there is anything else I should look out for in the next few days. She hasn't taken any food since a day before she went into labor. She even refused a nice snack of jerky. She has been drinking water pretty steadily though.
