It definitely sounds like you should get your blood sugar checked. Call the doc and make an appointment. Until that time, if you know someone with a home glucose machine, you could check your own blood sugar level just to see. The lab check will be more accurate, but a home test will at least give you a ball park and let you know if something is up.
