First appointment...when to go

I just found out I was pregnant about 2 or 3 weeks ago. I lost insurance when I moved a month ago and now Im guessing I'm about 6 weeks pregnant. When should you go to the doctor for your first check up? I don't have insurance starting until next month and I don't have much money after having to drop $300.00 for a month of insurance. By the time it kicks in I'll be closer to 10 weeks, is that too long to wait to go?! I'm so stressed out, I've already miscarried a few years ago right around 14 weeks...I don't know what to do.
