You likely have something infectious, a stomach bug, or travelers diarrhea. Dr Google can be a scary thing, and self diagnoses are nearly always wrong, so try not to freak yourself out and drive up your anxieties, if possible. There's many things that can cause diarrhea and IBD and UC are the least common reasons for that. I'd see if it passes in 3-4 days, if not see your general practitioner (primary care doctor) who can do a stool test to check for infectious causes, if found antibiotics often clear up the one time episode and then you never have to worry about it again.
Prior to my diagnosis of UC, I had a whole lot of blood in the toilet bowl (bright red toilet water every time for weeks), and that is the most frequent thing that sends us out to seek a diagnosis. As you do not have blood in the toilet water, then I'd say it is very unlikely you have UC.
