Vomiting

KK • Blessed beyond measures.,. Life is just beginning for me
I am not keeping anything down but bread. Anything made with bread like pizza, bagel and cream cheese and toast. I am sick every single day and this is my 4th pregnancy with one child born i am ten weeks but believe I am close to twelve weeks this coming Monday. . I have tried ginger ale, and crackers and the sea bands. Neither are working. Please any advice would be great. TIA
