How often do ice ages occur? Are we due one?

I’m just watching Ice age with my kid and it prompted this thought, just curious.

For the last 3-ish million years we've been in an ice age with a cycle of 100,000-year glacial periods and 10,000-year interglacials. So we're still in an ice age, just a warmer period. For most of the last half-billion years the Earth has been warmer with no ice caps, but there were a few other ice ages, notably during the Ordovician and Permian.

It's been more than 10,000 years since the start of this interglacial, so you'd suspect we were due for another glacial, but the timing of these periods isn't that precise, and obviously human influence has caused us to dramatically deviate from the natural climate cycle.
