Severe nausea and emotional upset

Holly
So I was feeling great until I hit the middle of week 5 here... Now I'm on the couch most of the day wrenching into a trash bin... Feel light headed when I stand... But not actually throwing up. Feeling this way has made me really weepy for whatever reason. The thought of being poked and prodded and having a long appointment on Monday (my first appointment) makes me feel sick. Been sipping gingerale, and Gatorade. Can't drink my morning cup of coffee anymore, makes me heave. Got ginger candies and crackers too... Is there anything I'm not thinking of? I don't want to feel this way when I should just be happy. 
Any advice would be great. Thanks girls 😷
