you should also take measurements and maybe have an article of clothing that you try on once in awhile to see how your body changes. The scale is important but is not the "be all end all".
I'm struggling with getting myself to drink water for some reason, are you drinking water, they say if you don't get enough water your body will actually hold onto water and it will show a weight gain, but it's because you're dehydrated, not actually "not losing weight"
best of luck
