Gagging and vomiting daily

#firsttrimester Hi mommy out there, I’m in my week 11 day 5 now. Still experiencing very bad nausea! Been retching and gagging day and night non stop. Sometimes it’s just my gastric juice coming out , sometimes it’s just air. If I eat more I ended up vomiting my meal. Does anyone experience this??? I was hoping the morning sickness to goes off after week 12…..
