Weird Discharge?? Help me please!!!

is it normal to have weird discharge when you've missed a period. I didnt get mine this month and since i was supposed to have it, ive had a weird color discharge and idk what this means. Im only 14, and I'm still a virgin. I also cant ask a female figure in my life because I dont have a mom or anyone else to talk to. And if it is an infection, how do I go bout telling my dad???
