Serious question! terrified and scare help!?

ok its a little gross but here i go, so i have had diarrhea for 2 days the first day it was normal but yesterday my mother bought some chinese food and i ate a lot of red meat like i think they put dye because it is soo red! so my stomach hurt and i drank red gatorade, well i ate some more meat again that night and today i woke up with red diarrhea! i think its blood but maybe its just the meat because it doesnt look like poo its like tissue but red! when i wipe is kinda red and brownish and i am scared :( i really dont know what to think i have no other symptoms but yeah i thought it was the meat? but i am not sure! since it is the weekend the doctor is closed so i will have to wait but what do you guys think it is? i have never in my life been sick of anything so i dont know what to think. Thanks for your answwers :)
