Quick easy experiment is to raise your saddle by about a 1/2", see if that helps. You should be "almost" straightening your leg completely on your pedal downstroke- almost, but not quite. You should NOT be able to touch the ground with your feet while still sitting on the saddle. If your knees stay too bent while riding, you will get knee pain in front right above the kneecap.

Congrats on the clipless!! Great going!
