120 fasting!

My meal numbers are consistantly in the normal range, but usually my fasting numbers are slightly high - ranging from high 80s to low 100s. This morning I woke up with a fasting of 120 - 17 higher than any of my other fasting numbers.

Is this out there enough to be concerning enough to call my doctor? Or should I wait to see if it goes back to normal (for me) the rest of the day/tomorrow?
