Never been this sick please help 🤢😭

Hi everyone so I recently found out I’m pregnant again I currently have a almost 15 month old son & when I tell you ever since I found out I was pregnant I feel nauseous & queasy 24/7 I’m talking from the moment I wake up to the moment I go to sleep nauseous & it’s miserable I literally just got done throwing up & im so sick of it it’s starting to take a toll on me!! 😣😢 i definitely wasn’t nearly this nauseous with my son so I called the place where I’m gonna have my first drs appt but they said they can’t do anything for me because I’m technically not a patient yet (my appt is on June 4th) so she said I can only go to hospital or urgent care but I also am working so I mean can anyone give me any tips or advice on what I can do for this nausea please & thank you 😭
