Either way...well see how it takes today.
That may help. By your description it sounds to me that your bouncing in the saddle or are firmly planted to your saddle. Try to ride the bike raising up slightly over all bumps/cracks in the road, not just sitting on it and work on smoothing out your pedal stroke.
