Since you only have 7 months of credit history, it's not surprising they you're not prequalified; lenders just haven't had time to put you in the system yet.
6 months is probably the first big jump in establishing credi, though atleast 1 year history looks far better.
That's good that your util is at 2% instead of 0. You should always try to keep a small balance on 1 card. Having 0% util can actually damage your score, so try not to let that happen.
