I agree with x2. Check your husbandry duties first. Bp's can go six month's or so without eating.
Are you feeding live or f/t? Just continue to offer food. If, you are feeding f/t mice/rat's? You can try and leave one in her tub or whatever your housing it in overnight. This is what I did with my normal 0.1 when she wouldn't eat. It was gone in the morning and her last meal was live.
