Help...Please

I'm 15 years old and I'm having blood come out of my vagina 10 days too gosh damn early and I need to know if I'm going to need a doctor or if I'm gonna die or what the fuck is going on because I'm freaking out. I was at the doctor's yesterday and I was fine and my period tracker is saying I'm experiencing mid cycle spotting g or what ever but this has never happened to me before. Please help me.
