What can I do to get off this plateau?

I've lost about 9 kg (20 lbs) since Christmas. First I only reduced my unhealthy snacks and candy. Then I started eating more healthy foods in general and the last month I've used MFP to log and started to work out more. But my weight loss is stalling and I seem to be plateauing.

Am I doing something wrong? I've ordered a fitbit one, so I'm hoping I can get a clearer picture of what my actual calorie use every day is. I'm also planning to do more workouts.

I've opened my diary, but I guess a lot of the foods are different since I live in Norway. You can still see my macros.
