Diarrhea, abdominal pain, nausea?

I started having diarrhea on 11/25 and still have it today, 12/8. It started off like normal diarrhea, then over time changed colors and texture repeatedly. It got to where I was going every twenty minutes and sometimes didn't have to do anything but still felt the urgency. I have kept well-hydrated so that isn't a concern. The past two nights I have finally been able to sleep the whole night through, but my stomach has started mildly hurting (ascending, descending and sigmoid areas) and tonight I started becoming a little nauseated. there has been no vomiting as of yet. The diarrhea has slowed to almost a normal amount of bathroom visits daily, but still isn't a healthy texture. Once I heard gurgling on the descending side. I gave it a light squeeze and lost two pounds. I was stubborn and able to deal with all this but the nausea is too much. I am going to go to the doctor this weekend, but in the meantime, I'd like an idea of what I could possibly be dealing with. Surprisingly, despite all this I feel just fine the majority of the time, even awake, energetic and happy. Thanks for your help.
