TMI WARNING

I am always constipated. For the last year I've been used to going on average once a week. All of the sudden yesterday I started getting stomach cramps and very frequent loose stools, but not d*. It's been 24 hours since it has started but my stomach just started to gurgle and cramp more, and I'm feeling really out of it. I also get slightly n* every time I have a BM. I haven't had any changes in eating habits. The sv* is going through my office like crazy, so I'm getting paranoid about that.
