Health coverage after losing my job: marketplace or Medicaid? - first time posting

I have 3 weeks left on my current insurance and I am comparing options. I have read a lot of threads here and could not find my exact situation. I do not want a gap in coverage. How fast did coverage start?

Compare the monthly price with the deductible. A cheap plan with a huge deductible can cost more if you need care.

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