You are probably gaining some muscle which might account for a bit of the gain, plus some water if time of month is approaching. Your weight and measurements are no good to measure on a day to day basis, you can't really develop a true sense of your progress based on the performance of one day. I'm sure you know that but it is easy to freak when you just look at the numbers and not the overall picture.

Don't think that you are doing yourself any favours by not even eating the 20 grams of carbs. You are probably stalling out because you are not getting enough carbs. You need them. They are not there just for fun. Your body needs the fibre in them to clean you up from the inside out. Look at your books again, rethink your program, and try not to be in "DIET" mode here. I think I do that sometimes, think that the more extreme I take things the better it will be, exercise harder, eat even less...it leads to burn out and less success.

Keep going, give it a few days.
