What do I do??

6 weeks 5 days and haven’t kept anything down since last Thursday other than occasional popsicles. Throwing up 10-15 times a day, only peeing once a day and no nausea meds working. What do I do?? Ob appointment in 3 days. I feel so miserable and helpless. Went to my main hospitals stand alone ER and they were absolutely no help. I’m pretty sure they gave me the wrong iv nausea medication ( I asked for promethazine because that’s the only one that works for me and I’m almost certain that gave me reglan because it makes me so anxious and I was nearly on the verge of a panic attack the whole time). I was also complaining of cramping and spotting due to dehydration and they gave me no update on my ultrasound only saying that everything looked “fine and that they think it was one baby and think they heard a heartbeat of around 130?) I could barely stand on my way out and they offered no assistance. They just prescribed the same medication that I’ve already been taking and sent me home. I’m at a complete loss. I’m not even functional right now. My husband has been having to help me stand and even sit up. I can barely hold my phone. Does anyone have any advice???
