If turns out im preggo, no health insurance yet, what to do?

I am going on 5 days late with a very high chance I am pregnant, testing again after this weekend. I do not have health insurance (I'm 21, 3 semesters of college to go!) I know prenatal vitamins are something i would need to start taking right away... so until I apply for medicaid & potentially get accepted, I will need to take something! Any advice?
--------------------
Any over the counter prenatal vitamins from the drugstore. No more caffeine. No ibuprofen, just take Tylenol if necessary. No sushi. No lunchmeat. No non-pasteurized juices or cheese. Don't stress. That should cover you until you see a doctor. Oh, no cold medicines....Robitussin if you get sick.
