Seriously depressed.

Don't know what to do. My Dr office called me and let me know that my insurance is refusing to cover pregnancy and delivery so now I have to turn to the state. Which would be fine but... I am high risk, have no idea how far along I even am(just an estimate), and I had to cancel my appointment for an ultrasound.... Even though that was supposed to check for heartbeat. What do I do now :( I can't apply for Medicaid until the end of next week.
