How much you should eat is dependent on a number of factors:
Time frame to lose by
Amount and type of exercise
You touched on one when you said that you brought your time-frame forward and the result was a lot lower calories. A lot of people are unrealistically aggressive where it comes to what they want, and it sounds like you may be one of these. A healthy weight-loss is 1-2lb per week, altho' if you are a lot heavier, you could realistically expect to lose a little more than that initially. You must remember, too, that there will be times when you DON'T lose any and may in fact gain a little. This doesn't mean that you are doing anything wrong - it is just the way it is.
An average weight woman who is sedentary shouldn't eat less than 1200 calories daily. This is mainly to ensure that they get the nutrients that their body needs. Apart from calories, we need a variety of food, including fruits and veges. When I went to have a wee peek at your nutrition tracker, I noticed that you are very low in that department. I realize that you belong to a low-carb team, but you can still fit in some fruit and veges. Some don't have tons of carbs, and veges generally have less sugars.
A woman who is over-weight, and/or exercises, needs MORE calories. Some need around 1800-2000.
