I just changed jobs and now I'm without medical coverage. I am going on 7 weeks. My doctor referred me to a local clinic while I don't have medical benefits. They only have a voicemail to request an appointment. I called Monday and again today. No one is calling me back. I'm wondering if I should just go and make an appointment in person. I'm really worried about having to go there. Does anyone else go to a clinic?
