Is calorie intake correct?

A lot of people think of losing weight as spending as short a time as possible at the lowest possible calories you can manage, but that's both unnecessary and very often ineffective. Your body needs a certain number of calories to stay at its current weight. Given what you said and assuming you are of average height for a woman (5'4") you currently need to eat somewhere around 3000 calories to stay at your current weight. This can vary a bit on either side, but for most people with your stats, that's going to be about right (see https://www.supertracker.usda.gov/bwp/index.html). If you want to lose 1 pound a week, you need to eat 3500 calories less per week (3500 calories = 1 pound, roughly speaking). Since you're starting at about 3000, that means 500 less a day, or 2500 calories.

Now the problem you're looking at is that people are really bad at estimating how much they're eating, even when they try to count calories. Many diets therefore trick you into eating less by cutting lots and lots of things out of your diet, or giving you a really low goal (1200, anyone?) with the assumption that you might not hit that low, but you'll probably eat less than you're eating now. What I like about MFP is that it puts the power in your hands. You just need to figure out how to use it. Log your food as accurately as you can, use a food scale at least at the beginning ($20 on Amazon), read all the stickied posts here (http://community.myfitnesspal.com/en/discussion/10300319/most-helpful-posts-general-diet-and-weight-loss-help-must-reads), and be patient.
