Depending upon how far along your crepe mytrle is in this seasons growth, you possibly could cut off some potential flowers. But, as they bloom on new wood and bloom continuously once they start, I don't think pruning now will set it back too much.
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and proclaiming...."WOW What a Ride!!" -Mark Frost
