pregnant!!

I just found out today that i am pregnant with my first! i am beyond excited but also nervous!!! i know i’m not far along at all so i’m super stressed about something going wrong or having a miscarriage. i also don’t know what to do as i’ve never been to an obgyn i have a dr app with my family doctor 2 weeks from today (that was already scheduled) i know i need to schedule w an obgyn but didn’t know if there were any prenatal vitamins i should grab from the store! please leave any advice you have !!!
