Nausea

I'm almost 9 weeks pregnant, I've been working as a Store Manager for the past year working 45+ hours a week. My nausea is constant, nothing has worked for me to get relief, I'm constantly in front of a trashcan crying. Working has become the biggest challenge for me. I'm a manager & all my employees watch me puke and cry all day and that's not a good leader for them, they're suffering with me. I'm not sure if I should find a new job where I'm not in management or what, I cant do this every day, I cry in front of customers and it's so embarrassing. Anyone have advice for me?
