I am 3-5 weeks into pregnancy. i am a tourist and don't have insurance or enough money to see a doctor. i can get medication. what do you recommend?

Prenatal vitamins: If you are doing well, then you can probably wait till you return home to see a Dr. You should probably start prenatal vitamins however. That is available without a prescription at any drugstore/pharmacy. If there is a problem with your pregnancy and need to see a doctor without insurance, there are "urgent care" clinics that are less expensive than ERs that may be able to see you.
