Health coverage after losing my job: marketplace or Medicaid? (update)

My employer coverage ended at the end of the month and I am trying to work out what to do as a welding apprentice. 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.

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