First of all congratulate yourself for starting to get yourself healthy by exercising!! That is great! You have to keep in mind that when we exercise, lean muscle mass is being built (even in women but not as big as in men) and it weights more then fat. Do not use a scale; use a measuring tape to see if the exercising is making a difference. Trimming ½ inch, or 1 inch is great! Your clothes will also be a tell tale sign as you become trimmer. You did not state what type of food you were eating, just the amount of calories 1200-1500 calories per day. What is important is what type of foods you eat that make-up that calorie intake. Eating healthy is eating a lot of fruits and vegetables. Eating daily high fiber breads and cereals (oatmeal), ¼ cup or less of nuts (walnuts, peanuts, cashew), low fat meats (chicken, fish, loin of pork) or non meat sources (soy products), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), and fat free or low fat dairy products (skim milk, 1% milk, low fat cheese, low fat yogurts, low fat soy milk/yogurt). You are consuming adequate quantities of fluids. If you are still concerned about not losing weight or trimming inches off, see your MD and get blood-work done including your thyroid, which regulates your metabolism. Hope this helped.
