My first pregnancy! What should I do/know?

Melissa
I just found out two days ago that I'm expecting. Doing the math from the first day (oct 25th) of my last period I'm 5 weeks. I do not have a doctor yet and would like to know if anyone has advice until I see one? I'm not ready to tell people because it's so early but I would like advice. I am and have been taking prenatal vitamins for months. Thank you.
