First trimester feels like the flu

Does anyone else just feel like they have the flu with all day nausea? I didn’t have symptoms this bad with my daughter, I just feel so miserable and I’m vomiting more this time as well. I can barely function taking care of my toddler daughter 😞 I also have no interest in eating whatsoever but I try to eat bland foods. I have a wedding to go to tomorrow that I don’t want to miss but idk if I’ll be able to handle it and I certainly don’t want to be physically sick in front of people!
