Ummmm I just had 2 abort at about a month along and there was not even half that blood. I'm thinking maybe he rage so check mine also acted like the do every day......I'm thinking vet 
Uterine bolus is to flush toxins out of her quicker.She's still uncomfortable today and no one has seen her eat. I have her b complex, probios, and my teacher put a uterus bolis or uterin bolis in as far as she could get it. I don't know what it's for or if that will help her. I also took her temp and it was like 102 something... Is that low?
There was another pile about that size alsoThat sure is a lot of blood for just a abortion at a month along.I agree with the banamine for pain. I would NOT do aspirin since its a blood thinner
