I need some advice on what just happened..

Today I felt as if I had a bladder infection, symptoms such as a burning and all the good stuff and peeing frequently. But I just went and had a little blood on the toilet paper. I thought it was weird I dont have my period for 6 more days and it would be weird if it started early. Im not sure what it is. What do you think it is? Could I have peed blood or could it. Maybe be implantation bleeding? It was just a tiny tiny bit. Like a like red color.
