I buy things on credit card, and pay the full amount off, but my credit score is going down instead of up?

I have nothing else my name expect this credit card, and student loans that are not due yet because I am still in college.

    Something weird is happening. Mine goes down when I have a higher balance and up when I have a lower balance. I've never had any debt either, just paid the bill every month .
