Major period question /: ?

Okay so I'm on my period and I'm 13 and this morning I was laying down when I felt Like I had to go pee so I stood up and I started to come out so I rushed to the bath room and the blood cane out like ketchup ughhhhhhh it was horibal and it does this sometimes but this is the first time it's done that. Is this normal ? Thanks for answering ~ Mia
