Carb intake too low?

Ok...I get this ammonia smell when I sweat. I researched it and it says when your carb intake is too low and protien too high your body uses protein as fuel instead of carbs which converts to ammonia. But I dont think im eating to few carbs...

On average I consume 120-140 carbs a day and 90-120 g of protein...im on 1200 cals a day (I dont want to hear eat more cals, Im doing good on 1200 so im staying there)

Do I have an improper balance of carbs and protein?
