Health insurance gap after a layoff (Oklahoma City)

I have 3 weeks left on my current insurance and I am comparing options. I do not want a gap in coverage. How fast did coverage start?

A free navigator at a community health centre walked me through my options. It took an hour and saved me a lot of guessing.

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
