Checking my last day of health coverage

I am not sure what date my benefits stop after being let go as a sales associate. It has been a long 10 weeks. I have an appointment next week. Did coverage match what HR said?

Keep a copy of any coverage confirmation in case of later disputes.

Thanks for writing this out. I went through something close to it 3 months ago, and it settled down once I kept a simple log of every call and form.
