Whats wrong with my body?

Okay, as gross as it sounds, I have been going #2 at least 3-5 times a day for the past week, and for the past day or two, I been just barely been throwing up a little, like in my mouth. I haven't been taking any pills, or eating anything different, I have searched the internet also, so like, should I tell me doctor. And no, I haven't been sexually active and I'm not pregnant if that's why you think I keep puking.
