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

My employer coverage ended at the end of the month and I am trying to work out what to do as a dental hygienist. I worked as a dental hygienist before this. I do not want a gap in coverage. How fast did coverage start?

Losing job-based coverage usually opens a special enrolment window, so check the deadline on the official marketplace site. I missed it by a day once and regretted it.

Thanks for writing this out. I went through something close to it 4 months ago, and it settled down once I kept a simple log of every call and form.
