This is my second pregnancy and im about the same... i find that ginger gum helps a lot so that I can get something in my tummy! Also maltomeal and a coke. Slso, they have sea bands for morning sickness that push the pressure point to relieve nausea that work great!
The doctor will.give you some medicine to take off the vomiting and nausea
I was the same way nothing helped my Dr finally had to put me on a prescription so that I could at least stay hydrated. If it's really really bad you might want to talk to your Dr about that. But you can try ginger ale ginger candy crackers
