How should I interpret a CBC with slightly high WBC and borderline platelets?

[Aurora75]

I recently had a routine physical, and my complete blood count came back with a slightly elevated white blood cell count and a borderline low platelet count. My doctor said it's likely nothing to worry about but wants to recheck in three months. I'm trying to understand what these values actually mean in context. For others who have navigated ambiguous CBC results, what factors did your doctor consider to determine if further investigation was needed? I'm particularly confused about how things like recent stress, minor infection, or even hydration can influence these numbers, and whether I should push for more specific tests now or simply wait for the follow-up.
