Nausea like crazy

Mary • Married 5/26/12. Police wife. Emergency room RN.
Anyone else really nauseous so early?? I'm a day shy of 5 weeks and I seriously am so nauseous. Really only nausea but I have thrown up 1-2 times... I found out on Monday I'm pregnant with my 1st... I figured I'd call the docs office on Monday but idk if it's mostly psych or if a lot of people get nausea so soon..
