Too many calories??

Hi everyone. I have been trying to lose weight for all my life it seems but have been involved in a weght loss program through my health insurance for the last year. I lost close to 30 pounds and got burnt out on spinning and let myself get discouraged and I have gained about 25 back. As much as I was exercising I thought I would have lost more weight than I did. When I signed up for MFP I selected that I wanted to lose 2 pounds per week and they gave me a calorie goal of 1,800 calories a day. I have been excersing at least 5 days a week cardio 3 days for an hr (burn around 5-600 calories per day) and weights for 30 mins 2 times (around 150-200 calories per day)a week. I still am not seeing any weight loss. Is 1,800 calories a day too much? I don't want to drop to 1,500 only to lose at the same almost non existant rate that I am now. Am I doing too much at the gym and building muscle and not seeing that initial weight loss come off like many do the first couple of week? I have been religiously tracking with MFP for almost 2 weeks. Any advice would be greatly appreciated. Thanks.

**Let me add, while i have lost 5 pounds in 2 weeks which I know is more than the 2 pounds that I put I would like to lose per week, I always end up with calories left over at the end of the day. Also, with over 150 pounds to lose, I would think I would initially be dropping weight alot faster than I am right now. Thanks again.
