Severe naseau all.the.time

This is my 2nd pregnancy. My nausea was bad in the first one, but this 2nd time around it is incredibly worse. I've only thrown up 2x. Mainly my naseau just sits and I can't throw up. It is like I have constant motion sickness. I'm 7 wks and 3 days. Since yesterday I literally have been in bed exhausted and overly nauseated. Is this normal? I even tried ginger ale and ginger tummy drops. Nothing is working.
