Period without blood? Please help? - can u have a period without blood

I do not know if I really am my time, but in the last week or two, I was very, very bad mood, cramps and loss with a big white ... bloodless .. I am very late in my period. I am not pregnant, because I am a virgin, but is very rare .. Clock precisely, I think I had ovarian cysts, so that I do not know if this has something to do. Why is all white discharge but no time? Am I merely irregular? (I'm still a teenager), Help!
