Peeing blood

Kara
I'm not due my period for another 11 days, I just went want to the toilet and peed a out a little blood but it wasn't muscusly like menstrual blood. Then when I went to go put in a tampon, I wiped just to make sure there was nothing there and there was nothing there at all. It was like I had just peed normally. Is there something wrong with me? Should I be worried?
