I don't think there's anything going wrong at all. 10 lbs in 2 months is actually quite healthy!
For reference, I am following a very similar plan--burning 350-400 cals 5 x week, moderate weight training 3-4 times per week, staying within about the same calorie range you are. Since Thanksgiving, I have lost about 9 or 10 pounds as well. So there you go
If you feel yourself plateau-ing, vary your workouts. E.g., circuit training one day, 30 min easy jog the next, sprints the day after, and so on.
1 to 2 pounds per week is healthy and normal. You're doing great, so keep it up!
