With little weight to lose the road will be longer for you, Anne. 15 lbs represents 100% of your goal, for someone with over 100 lbs to lose, 15 pounds is a drop in the bucket; think percentages instead of pounds and you'll feel better. 7 lbs lost for you will be 50% of the journey

I see you've read and are doing PP; have you used the formula at the front of the book to figure out your % of body fat? 125 lbs on a 5'6" frame may not be a reasonable goal. Muscle mass, frame size and age will all effect your ideal weight. You may be a lot closer to your ideal weight than you realize. Using % of body fat will help you figure that out.

I would give it more time and I suggest starting up a Journal in the bootcamp section of the Forum where you can keep track of what you're eating and drinking and we can help spot some possible troubles.
