Me again! 🙄

Sooo yesterday I posted that I was dehydrated and asked if i should go to The ER. So i did. Was there for 8 hours. They gave me two IVs and did a sono to make sure baby was ok. Everything was fine. And I felt better. Well came home ate some chicken noodle soup because I was starving and it came right back up. Now this morning I took two bites of toast, that came right back up and now just ate a damn saltine cracker and that came right back up. I’m seriously just so scared. I don’t want to harm my baby but I’m so fed up. I’m guessing I just possibly have the flu but idk what to do. Can someone guide me in the right direction? Please and thank you!
