For the past two times I've gone to the bathroom tonight, there has been white and red things in my stool. Like, there wasn't much regular brown fecal matter, the small round ones I guess, but that's it. Anyway, when I flushed I noticed that one of the white puffy things was sort of stringy and long. This has never happened before and I'm pretty worried about it. I haven't been eating anything weird today, besides an omelet. The day before that, parmesan chicken. I don't eat a whole lot of fiber which I know is a problem, but could this be the cause of it or is it something way more serious?
