Most figure/fitness gals I've talked to go no lower than 1200-1400.
You are likely eating too little. Your severe fat restriction is also a problem. Personally I would increase your intake by adding 20-25 grams of fat and 50-75 grams of carbs.
If you have the money I would contact Layne Norton (str8flexed on the forum) and hire him as a contest prep coach. He is well known for bringing in his athletes on time and being very successful with contests. He is an expert in this field and I am sure he could help you out.
