Gina, that is so awesome about your work out schedule. I wish I could be as motivated as you and get out there and MOVE!!
Do you realize that by all your work outs, you are building muscle? That weighs more than fat. So you are indeed losing the fat but your weight will slow down a tad (or even stay level) while your muscle tone is increasing.
Don't give up....Keep going girl and all of a sudden one day you will look into that mirror and go "WOW!!"
You are doing GREAT!!
