I had a similar experience when I started too. I lost 1.5 pounds in my first month! I was pretty discouraged but I just kept going and then the pounds finally started to come off. Believe it or not, lack of sleep can have a lot to do with weight loss. I didn't believe it at first but I was sleeping very badly at that time and once that improved so did my weight loss.
I also think that since you don't have that much to lose that it might be slower for you. You won't see results like on the Biggest Loser where contestants lose 10 pounds in a week!

I bet if you stick with it, your body will definitely change for the better. A great thing to do is take your body measurements because resistance and jogging will definitely shrink you but might not show up on the scale.
As for the calories, you might want to consume a little more (check out your daily needs here
Calorie Calculator - Daily Caloric Needs) and be sure that your protein intake is over 30%. That helped me a lot! I used to consume a higher percentage of carbs but when I changed the ratio in favor of protein, the pounds came off much more easily. Your muscles are fed by protein and the more you feed your muscles the more fat you will burn.
Hope that helps! Keep up the good work and you will get the results you want!
