Hey im from the UK my 5th pregnancy I use ginger like ginger biscuits or ginger ale and in cooking it helps to stop the nausea... i hope this helps you :)
My go to was peanut butter or peanut butter and jelly sandwiches. That peanut butter was very satisfying, offered protein, carbs in bread. It seemed to settle my stomach. A midwife gave me the advice to eat this. good luck
I highly recommend different types of bone broth. It's so incredibly good for you. So many vitamins and minerals and it taste like chicken soup :)
Anything bland and non greasy should help a lot. I pretty much lived on bone broth those first few weeks. Worked my way up to lightly seasoned grilled chicken,brocolli and brown rice. (Small portions) it's all pretty plane so it was good. Also try some smoothies
Plane banana and apple with some oats, milk and ice has been really good. Or maybe homemade slushis? Just ice with fruit flavor like cherry lime?
