Carb intake seems too high and that you're trying to maintain eating them. Remember the general rule is 50-100 for weight loss and 100-150 for maintenance. Which range do you think you're in?
100 grams creeping up to 120 is really maintenance range and you won't lose much doing that.
The thing with the ranges are is that they are guidelines. You have to find out what works for you. Try decreasing to 50 grams for a week and see what happens.
