Nausea problems

Hey ladies! I’m about 6 weeks pregnant and have had the worse two weeks ever. I haven’t been able to hold down any food or drinks at all I’ll drink/ eat something an 5-10 minutes later I’m throwing that exact thing up. My lower part of my stomach has been in pain that is constantly hurting. I’ve went to the doctor and they had me sit there for 7 hours just to go home and feel the exact same hours later they told me to drink a lot of water but I can’t even hold that down.. Any advice that can help would be greatly appreciated I don’t have a obgyn yet still awaiting Medicaid and I’m just tired of this feeling I want to be able to eat a big fat burger with no problem of throwing up or stomach pains. 😭
