Diarrhea issues 😷

I'm sorry if this is really gross!!!! Last night I woke up at 3am and had to run to the bathroom and had a bit of diarrhea. It was weird because it was orange/yellow. I went back to bed and woke up this morning and almost immediately had to go again, but the only thing that really came out was this weird mucus/orange mixture? This is so TMI disgusting I apologize but idk why this is happening. I don't feel sick at all. Yesterday was my cheat day so I had pancakes for breakfast, salad for lunch and 1 chicken nugget and McDonald's ice cream (only half) for dinner. My sister ate the same thing and she's not sick. I think i may be miidly lactose intolerant but this is the first time it's bothered me in a while. Should i be concerned?
