I'm 16 weeks pregnant and I have been nauseated for about 4 days now non stop I also have been throwing up constantly. What should I do? All I want to do is cry for how bad my stomach hurts.

Have you tried ginger? That helps with nausea, especially in pregnancy.

Also, if you have been unable to keep any fluids down for 4 days, you need to see your doctor. You could be severely dehydrated.
