Reading HPT

Today I took two Walgreens brand pregnancy tests. One when I first woke and the other a few hours later. The tests came back with a line in each box, but the lines where not always in the correct direction and 20 minutes later the "pregnant" lines faded away.
My husband then went and bought a First Reponse digital which came back as negative. Should I wait a few days then test again? Thoughts?
