Don't worry, it's not a stall. Weight fluctuates daily and that is why most people recommend weighing only once a week. If you were truly in a stall you wouldn't have lost any weight or inches for 6 weeks while staying strictly on this woe (no cheats).

Weigh yourself once a week, increase your water (never hurts to do that), increase your exercise, and take your measurements. In fact, ignore the scale and go only by measurements.

Good luck
