Hi Briela, a womb infection, known as pyometra, is a very serious infection. The symptoms are exactly as you describe, and you did the right thing in taking you bitch to the vet. It can be an open (discharging) or closed (no discharge, and more dangerous). I lost a bitch years ago, to pyometra, so keep up the vet treatment. Hysterectomy isn't always neccessary, but I think I would choose it under circumstances like this.
Best wishes,
