You're correct that that weight at your height results in a BMI of 18.3; underweight, but not excessively so.
However, if you're working out so much that you have significantly more muscle mass than the average person, BMI is even less useful than it is for most people. Since muscle weighs significantly more than fat, professional athletes in peak physical condition with minimal body fat can have a BMI in the overweight range. Therefore, if you have a substantial amount of muscle, your very low BMI could indicate that you have an unhealthily low amount of body fat.
Since you're only five foot tall, I assume you're a woman. One indication of undernourishment and excessive physical stress in women is the absence of periods. If you don't have regular periods, you really should take a serious look at your dietary and exercise habits.
In any case, regardless of what your BMI is and what clinical measurements would show your body fat to be, the fact remains that you have a very unhealthy attitude towards food. Sooner or later, you're going to pay the price for this.
I do have regular periods and I’m in good health. I have tried diets where I eat more but eat healthy everyday and I’ve found that I really can’t stick to it and completely avoiding unhealthy food makes me miserable. That’s why I have a cheat day and then compensate by eating less throughout the week.
