should I tell my work?

I'm freaking out. I've been lucky I work on the road and at home so I've been able to hide everything and throw up in my own bathroom.  And I've been throwing up a lot 3-4 times a day.  
This week my director flew in and we have a meeting. Of course at a restaurant that has nothing but meat (brutal aversion right now) and I was a huge whiskey drinker. 
Not sure if I should just tell them I'm pregnant.  My 90 days is April 2. And I'm 8+3
Thoughts?
