I second the suggestion of recording in Calorieking, even just for a week (it is free). The thing that caught me out was things like serving sizes of fruit and nuts.
Many apples for example, are actually "2 serves" of fruit. And a "serve" of nuts is only about 10 almonds, for example.
Depending what is in your museli, that could also be a source of hidden cals. Otherwise, it sounds like you are definitely on track with a fairly balanced and healthy diet.
The other thing to think about is how far are you from your goal? Your body will be different after growing and nourishing a baby. You are also 2 years older than before you got pregnant. So be realistic in your expectations.
