It could be stress and hormones. Have you had your thyroid checked? The first thing I would do along with making a doctor's appointment is to sit down and look at how many calories you are actually burning. If you have a heart rate montior this would help. Make sure when you set your fitness goals that you are putting in close to what you are actually burning so that your daily calorie range is accurate.
I don't know how tall you are, but 1300 calories seems low to me if you are exercising regularly. You could be sending your body into starvation mode. Try to eat at the top of your calorie range instead of the bottom. You could also try calorie cycling. Eat a different amount of calories each day. Your body could be in a rut. If all else fails try going off plan for a week. Give your body a rest. Eat good food and get plenty of sleep, maybe even two weeks. Then start again and see how your body responds.
Also, pay attention to your sodium intake. It could be your electrolytes are out of balance and you are retaining water. Do you drink at least 8 glasses a day? If you are sweating a lot you probably should be drinking more than that.
Good luck and I hope things get better for you.
Keep it simple. Slow it down. Appreciate everything.
