If your calorie in take is correct you are low enough. Sounds like you are at a Plateau and your body need time to adjust. If any thing I would add 100 or 200 calories. Maybe even alternate 1000 one day 1200 then next back and forth to see if you can break your plateau. Are you drinking enough water? (very important too) Hang in there you can do it.
