There was a layer of slime on my poop?

Sounds like you had a case of stomach flu or mild case of food poisoning. The slime material was most likely mucous which is found normally in the lining of the intestines, but when it gets irritated by something you ate or the flu the lining may slough off. The fact that the odor wasn't bad is a good sign and the reason the last one smelled may be that you finally are at the end of the inconvenience. I don't think you have anything to worry about, but if it continues for more then 2 or 3 days, then I would suggest checking with your doctor to make sure it isn't something more serious. You said that your stomach was not right the last day or so, so I am uming that you haven't had any problems with your stomach before now. Did you have cramping with your stools like when you have diarrhea? That too, could point to the fact that it was either food poisoning or the flu. Have you ate anything different in the last couple of days that was unusual for you to eat. That could point to a simple case of indigestion, even if you only ate something that was super spicy could cause something like this to happen. Like I said if your symptoms persist for more then a few days I would get it checked out and see if there is a possibility of something more serious going on or otherwise it was one of the three things I suggested. Hope this helps and you're feeling better real soon.
