Feel like OB isn't listening to me..

So I've been severely vomiting for the past week and not able to keep food or liquids down at all with a severe fever of 101-102. Before I found out I was pregnant I was supposed to have my gallbladder removed because it was causing me pain and blood vomiting spells which is starting to happen again as well. I have told my OB and all she keeps doing is prescribing me nausea medications and telling me it's normal. I want to go in to the ER after passing out twice already today from feeling so light headed but I don't want them to not listen to my issues either. What would you do?
