How far is your bridge hand from the cue ball? Is it a bridge too far? If you have a long bridge that is more than 8 inches, it may be too long. The long bridge provides more of an opportunity to sway your stick during the pool stroke. The sway causes the cue ball to create unintended english and/or off the line of aim. Unless you are a seasoned player with many years of play measure your bridge length to see if it needs to be shortened. Or use a stroke improvement tool such as coke bottle or Cue Track to see if you are swaying the cue when you stroke. A 6-8 inch bridge length is recommended for most players.
