Quandry......Im stuck on a Number

So Im really stuck on what to do. Ran my totals and only lost 2.6 for the whole stinking week.Just got done checking my measurements for the week. Not a freaking inch lost. I will have to call the doctor and see what she says. If maybe Im at a stand still at three weeks. Wondering if I should do p3 now or what? If nothing changes in the morning Id say that is what I will do. My daughter says the weight I am right now is the weight I was at for about two years, so she thinks I have plateaued. Im gonna research a way to maybe break it. AH I need help!!!!!!!!!!!!!!
