Does this merit an emergency?

I am 6 weeks pregnant and have been sick with flu like symptoms for 2 days. Vomitting and going to the bathroom often. I have lost about 5 pounds in that short time as well. Am I overreacting by wanting to go to Urgent Care? I am hardly able to keep anything down and any time I have vomited my stomach has been empty. The little food I'm able to eat is being processed through my body so fast I'm vomiting bile. Is this normal?

Update: Thanks for the advice ladies. I ended up going to Urgent Care as I was feeling super dehydrated and I had a low grade fever just over 100. They suggested an IV, but I was too dehydrated for them to find a vein so they gave me some zofran (which helped immediately) and now I'm home sipping pedialyte and finally eating what I can. Who knew pregnancy was going to be this hard this early?!
