I'm 6 weeks 5 days and for the past week I feel motion sickness and nausea until I burp.. It's so weird. As soon as I burp I'm fine. The only problem is I can't make myself burp so I am drinking lots of bubbly water to assist me.  I feel sick if I haven't eaten in a few hours or in the car. I haven't thrown up yet but I do have a fear one of these burps will just be vomit and I'm going to just vomit out of nowhere in public. It hasn't happened, but I do worry it will.
