Question and Rant, HELP PLEASE 😭

Okay so I'm 27 weeks tomorrow, and all day I've been sick. (This is the question part) I've thrown up 7 times today, starting around 11 this morning. I haven't really eaten anything today except some fruit snacks. I forgot my cereal that I usually eat in the morning and I usually don't was again until I get out of class at 4. But around 11 I threw up, and then 6 more times by 3:00. I've been drinking water but I can't even keep that down. Should I be worried?? Or is it just a flu maybe? I don't have any other symptoms except that. And, I was supposed to work tonight at 6, but I called off and found someone to cover me. (Now here's the rant) So I told my fiancé that I wasn't going to work and I explained why. His response was "idk how you're going to survive in the real world calling off work like you do" like, seriously??? I knew he was going to be a little annoyed but, come on! I said back "you could at least say 'sorry your sick babe' or 'at least you still went to class today'" and then I told him I had to go back to class and I hung up. I'm so annoyed. He calls off work for a damn cold! And I NEVER call off work. I'm so mad.
