brown/clear discharge?!

I'm 15 (idk if that will matter), andwas wiping just a few minutes ago and a clear discharge with dark brown streaks in it came out! I typically don't get my period till around the end of the month. But it's been known to jump around quite a bit, should I be worried about this, or is it just my period? HELP! I typically do get a brown discharge before my period. But it's very cloudy and sometimes in blood clots too, but never slimy  and majorly clear... idk what to think of it!
