Don't worry for now. When I got my first BP I was alarmed that he'd not shed for a month or so I think? But I just kept waiting and he eventually shed. At this point just wait as it's only been 2 weeks.
The age of your BP will be a factor as well. Hatchlings-early juveniles will shed more often than late juveniles and adults because they're growing faster.
You might want to contact the breeder/whoever you got it from and ask when it last shed just so you know when to call it abnormal. They may have the shed on record or be able to estimate when they last did.
