Morning sickness HELP MEEEEEE

I am 6 weeks pregnant and am continuesally sick I am managing to keep some fluids down but is this normal? To be sick so much I am worried that soon it will start to effect my baby! I have been to the doctors and am trying many different sickness tablets ( none of which are working yet) but nothing at the minute seems to take away the constant dick feeling. If it's not been sick it's the feeling of going to be 😔 please help me!
