We are also about 350,000 years overdue for a magnetic pole swap. [1]
Also, it cycles at 300,000-400,000 years not millions.

It could be. Since we've never seen a shift, we don't really know how it looks.
And a shift takes a few thousand years, so we can probably be centuries into it before it's clear what's happening.
I doubt the geological record is fine grained enough to tell fast oscillations apart from a slow drift.
I hoped "every few million years" was vague enough that I didn't have to look it up, but sometimes you gamble and lose :)
