slight coolant loss

have an 09 f350 with 14k. since my last oil change 6 months ago i have been keeping an eye on the level of coolant in the reservoir. at the beginning of the summer it was at the level at the bottom of "range", now when i checked it on level ground it is slightly below. I have not noticed any leaks since due to paranoia i look under the truck frequently.

is this normal and or something i need to be worried about?

i`m going in for an oil change soon, so I want to be prepared just in case i get "its completely normal" speech.

Mine changes 1"-2" depending on coolant temperature, and raises when you unscrew the cap (after shut down) and let the pressure off.
