Coolant leak?

So I checked fluids before a trip and the coolant reservoir was empty! Checked radiator and it was full.
Wife says o yeah the other day there was a blue puddle... I cleaned it up.
So I put new coolant in to check to see where the leak is. I see none. I drove it around and brought it up to temp. Park. No leak...
Park it back in drive way. No leak. Same level I filled it to. Stayed spot on temp while cruising.
I have never heard of coolant dumping from the plastic container and then having no leak after. Any thoughts?

Remove the lower belly shield and inspect the engine under side more closely. It's possible the leak is small enough that it would take some time before it becomes noticeable on the ground. Once you remove the lower shield it'll be obvious if coolant was/is there. It's a bunch of 10mm bolts and 3 or 4 rivet type push pins that hold it in place. Not difficult to remove at all but you will need to jack up the front of the car unless you're skin and bones.
