HELP!

I'm SO sick. I throw up all day and night, everything I eat or drink. I even throw up my nausea medication. I don't have any nausea. In fact, I'm so hungry, but I throw up everything I eat. I eat small meals, large meals, I've tried everything. Nothing works. After I eat, I'm fine for about 15-30 minutes then I feel like I've ate too much and I'm going to throw up, then it just comes up with little to no warning. I don't have a doctors appointment for another few weeks so what should I do? I'm almost 11 weeks and miserable. 😭
