Do I need to be on a stricter diet?

Weight loss isn’t linear, which is especially true for women due to hormonal fluctuations throughout your menstrual cycle. You should really evaluate your progress throughout at least one full cycle before panicking.

Having said that, simply counting your calories won’t help you lose weight if you’re still eating at a level which matches or exceeds the calories you’re burning.

Set up your MFP with your individual stats (height, current weight, gender, age, activity level and select a sensible rate of loss depending on how much you need to lose (the more you have to lose the quicker you can lose at the beginning) and see what daily calories that generates. Eat that amount plus some of your exercise calories and you may find that sets you on your way.

Did you make use of the MFP calculator? Trust the calculation, stick to it - calories in, calories out. Diets are of no use - find a healthy meal plan which suits your specific life style best, which you can live with long term; try to do some exercise. Relax, be patient - take it day by day, meal by meal. Cheer up!
