anything that helps please!

Okay, so I'm about 6 almost 7 weeks pregnant. My mom had this problem as well when she was pregnant with me. This is my first pregnancy and for the last 2 days I cannot eat or drink anything. I've gotten to the point I can't hold anything down. I've puked 6 times in the last 24 hours. I try everything I can to eat something and it just comes right back up less than 30 minutes. Please, someone help me. Any home remedies for this nausea/vomiting? Asap. I go to the doctors tomorrow for an ultrasound, will they give me anything?
