Why am I pooping so much?

It's been the same thing for over a week now and I'm getting a little annoyed. I have the frequent urge to poop all the time. I get the urge many times throughout the day. Almost every time, the urge is a "monkey gut" feeling where I feel as though I have to go use the bathroom immediately or I will crap my pants. Although, a lot of the time when I get those urges, I ignore them and they go away, and they come back later. Some of the time though, I do go use the bathroom because the urge to poop is more intense. This has been going for over a week, and it's not going away. At first, it started off as more of a diarrhea-type thing, and I figured that it'd eventually wear off, but obviously it hasn't. My poop isn't "hard", but it's no longer diarrhea either; it's in the middle. I haven't really pooped a lot when I do go, just small or moderate amounts. I don't understand what's going on; I'm not sick or anything. I've taken Pepto-Bismol a couple times, but it isn't working. Anything I can do to get rid of this? Please and thanks!
