HELP PLEASE!!

Elizabeth

I am almost 11w pregnant and I have the worst nausea vomiting. I constantly feel sick and dehydrated, I can’t even drink water I throw it up instantly. I’ve been prescribed a few different things from my OB none of which seem to work! Idk what to do I am snappy at work because I feel terrible all day I have been coming home and wanting to go straight to bed! Have had a lot of take out nights for my 7 year old while hubby has been in the field (army couple). Does anyone else experience this!?! Or have any tricks I keep the crackers next to the bed attempt to drink whatever I can but nothing seems to stay down. Toast comes back up to I just don’t want to continue to be snappy and distant from my family because I feel miserable and weak everyday! I had to go to the ER the other day just to get an IV it got so bad which I know is not good for baby either I just don’t know what to do!
