Hi Doc. Im 4 Weeks Pregnant. I Havent Been To

Hi doc. Im 4 weeks pregnant. I havent been to an o.b yet because im out of the country right now. Im suffering from morning sickness so i went to a pharmacy and they prescribed me navidoxine they told me its safe to take. But im having second thoughts also because i havent seen my ob yet. I dont want to take any kind of medication but im really having a hard time.
