I couldn't keep down many solid foods with my first. Ginger ale helped at the beginning. I then had to get some meds from the GP as that stopped working and I was becoming anemic so got iron and anti sickness tablets. However the anti sickness tablets either made me throw up quicker or killed off the sickness. It was Russian roulette. I also found at the beginning that a ritz cracker before sitting up or getting out of bed helped settle my stomach enough to move to eat some other bland food, usually peanut butter toast
Also u can get anitsickness tables from the doctors depending on how bad the sickness is x
Smelling some peppermint oil on a tissue should help I used this before :) or anti sickness tablets from midwife if it’s consistent x
