Period x2? Help!

Tiara
Ok girls... kinda freaking out... I had my period about a week or so ago, but today when I went to the restroom (Ik ik TMI) but when I whipped I found blood? Is this a period... Two times in a month?! Or do I have some thing up. No, not sexually active, not On the pill, nothing...? (Still a teen)  Any comments, advice? Muchh appreciated!
