Same problem here, no vomitting just nasty upset tummy everytime I eat. I have to eat so I suck it up! If I notice something specific makes it worse I avoid that.
You can buy preggy pops otc. Its suckers for morning sickness. They helped me a lot because I was allergic to the medicine the Dr gave me.
Eat crackers or bread first before you eat then if that don't work drink a boost I had to do that to keep my food down
