Is my diet and exercise regimen too much?

Currently I am a totally normal healthy body weight, but I'd like to drop 10 pounds. I eat 1000-1200 calories a day and I do a fairly intense work out for a little over an hour at least 5 days a week. I burn around 500-600 calories per workout. I don't seem to be dropping weight, but could that be because I'm gaining muscle? I notice my body is smaller but not necessarily weighing less. Should I up my calories?

I'm 5'8 and 140lbs and I want to be 130lbs and toned.
