Morning sickness

Montana

Can I have some advise on morning sickness please for all the ladies that get it. I’m constantly feeling the urge to vomit or throw up but it never comes up. I just get the really sick feeling before you vomit and it’s happening in the morning through the day and the afternoon. My dr said I can only take vitamins because I can still hold food and water down but as soon as I eat I get sick

I’m currently 7 weeks pregnant
