You didn't mention your eating habits, so perhaps that's the next step
You are exercising, losing fat, and gaining lean muscle; then you will not show weight lose because muscle weights more than fat. As we exercise we build lean body muscle mass which weight more than fat so the scale reflects no weight loss when in fact the body is trimming down fat. Measure your waist and hips as a guide for trimming down. The tape measure will measure loss of inches and your clothes will start to feel looser. As long as the body is toning up, there is weight loss.
