Oh My goodness,
If you have been doing everything exactly correct -- my guess is that you are retaining some fluid. That happens especially at a certain time of the month
Also things such as stress, lack of sleep, certain meds, or outside temperature can cause fluid retention. Don't worry the pounds which came back are not fat!! They are most likely water weight. I would suggest putting away that nasty discourager called
-- the scale, stay very very compliant, wait a couple weeks and then see what happens. If you are compliant you will lose weight. That's just a fact!! I know it is very very easy to become discouraged especially when we want something a great deal. You will lose -- put away the scale!!
