All day sickness

Rowena
Hi 
I being sick about 4 times a day and when I'm not being sick I feel so neauses. I felt so awful that I have had to call in sick to work. I am managing to keep most liquids and foods down throughout the day by little and often.
Can the doctor prescribe something to make this better as I can't keep being off sick! I'm 8 weeks, sickness started at 5 weeks and I feel it's getting worse and it's starting to get me down.
