Periods, periods, periods!!?

Ok so I have a few streaks of whitey yellow stuff in mu underwear everyday, sometimes orangey streaks (Once a tinge of red in it), sometimes I wipe and theirs this light brown orange white string of something? (What could that be? Is it discharge?) I have like 10 pubic hairs, hairy legs and underarms (Black and dark brown hair too). When do you thinknIm going to get it? BTW Im not exactly sure whether I want it or not.. And sometimes I have orang sort of pee?
