Morning sickness

Celeste
Hi ladies, today I'm 5 weeks and 6 days and it's my first pregnancy. I'm so filled with joy, however the morning/ all day sickness is making everyday functionality 100 times more difficult. I have been eating mainly crackers, before I even get out of bed and fruit mostly bananas in the morning as it's not so awful tasting when I throw up. I also feel full of acid and my throw up is frothy. Any advice is highly appreciated, please and thank you...
