No insurance? No dr visits?

I'm going on 5 weeks, and still haven't spoken with a dr/rn. I don't have insurance and this was an unplanned pregnancy. I don't know what to do. I really want to get blood work and u/s done soon but I don't have a dr or money to just go to a clinic/lab for such expenisive work. My SO is being as helpful as he can but he has insurance thru his job where as mine does not even offer insurance. I want the best start for my baby but don't know what to do about prenatal care. I already know I'm going to have an at home birth because of this, but I really want to be able to see a dr a few times! Ughhh I guess I'm just looking for ideas from you ladies. Anyone know any ways to obtain low cost prenatal care? We haven't told anyone yet and won't be until 6/21 so I can't ask for help from family, and even so I really wouldn't want too...
