Go to er. You might be dehydrated as well if vomiting that much and often. Also blood sugar could be low if shaking. If not er, then go doctors as soon as you can. Your passed the normal time for a 12w scan also which checks for fluids at base of neck if u haven't done that yet. I really think you should see someone hun they can also prescribe anti nausea tablets. People might start asking questions if ur always under the weather too if u don't want people to know
Have they put u on iron pills atleast it keeps your iron up and it could be morning sickness it's just doesn't mean in the morning it could be all day some women get it worse the others try some Ginger ale and saltines
