What do I need to do to care for myself while pregnant until I can get to a doctor?

I am pregnant. I just found out. I am trying to get health insurance to get into a doctor. I know my body and I am ecstatic. I have had twod BFP's one yesterday afternoon and one this morning. I have started taking folic acid. I want to take a prenatal vitamin and possibly progesterone because I have miscarried in the past do to low progesterone. What can I do in the meantime? I really want to get to a doctor to have all my levels checked and I am terriefied that I need progesterone to carry this baby. Is progesterone cream good to rub? HELP!!
