Doctor advice?

I'm 26. I haven't seen a Gynecologist since I'm was 18 or 19. And I've never had a regular doctor. the only time I would see a doctor is at an emergency room if something was horribly wrong with me. I just recently got of Medicaid because I'm about 6 weeks pregnant. Now a doctor will not see me till I'm 8 weeks pregnant. but I'm having some issue with that. mostly because I feel like I need to be checked to see if I'm even healthy. I have people in my family saying my blood levels need to be checked and so on and so forth. my fear is that I could be unhealthy and not know it since I haven't been seeing a regular doctor for all these years. but it's almost impossible for me to get an appointment because they say not until I'm 8 weeks. I've also been experiencing severe headaches. fatigue. And I just feel sick. not to my stomach...but I don't feel well. And I know some of this is normal. but it would just really put my mind at ease to hear it from a doctor. but they refuse to see me. So what should i do? any advice?
