Plateau

Back when I was in college, my roommate followed a similar calorie intake to that you are describing. She lost a significant amount of weight rapidly and ended up hospitalized for malnutrition. (Also note that she lost quite a bit of hair and she stopped having her period.). She spent another several months being treated for an eating disorder.

I would strongly suggest that you make an appointment with your doctor to discuss your weight loss goals and strategies.

Due to your rapid loss so far, I expect you would benefit from eating maintenance calories for a few weeks to give your body some rest from the stress of such a sharp deficit.
