Those aren't the typical symptoms of a fistula and you do realize fistulas aren't common with UCers? A fistula starts as an abcess. Abcesses are extremely painful and along with the pain there is generally a fever. It would be hard to miss an abcess or fistula. Also if she had a recto-vaginal fistula she would have stool coming out of her vaginal area. Again, hard to miss.
