Hon, look. You've lost 3 pounds.
Focus on the positive, because weight is just going to fluctuate like that. Water retention, time of month, who knows? If you give up every time the scale blips upward, you'll never get past the second week. You'll start to eat badly again and then next week the scale will be back where you started from.
Stay with your commitment. You know that your weight loss is going to take awhile. The gain didn't happen overnight. You have to be willing to stick with your plan for the long haul, regardless of what the scale tells you.
Keep going! You've got a good start!
