Anyone with faint lines but negative clear blue digital?

Christa.
I've had faint lines the last two days (10/11dpo) on both wondfo and frer. I stupidly took a clear blue digital in the middle of the morning today after a 6 hour hold and got a "not pregnant." Is it just too early? The box says 65% if you're 4 days out from expected af. Help please. See the picture of this morning's tests.
