nausea and throwing up at work

So this morning at 4am I woke up to drink some water. 30 mins later I woke up again and threw up so bad. I threw up a couple times today already. I wanted to take the day off as I'm dizzy af tired and feeling like crap. My husband was telling me I should still go to work even though I'm dizzy. I'm here at work now and I don't want to be here . Should I take tomorrow off? I'm just really new at this pregnancy . I'm 7 weeks today . Any advice on what I should do ? Please and thanks
