No appetite - help pls!

Hi mummies to be, i am just on my 6wk. I went to check up last week as i had brown spotting and felt sharp light pain on my right abdomen. Found that i had a polyp on my cervix and was given Duphaston pills. Im not sure if it is the side effect of the pills but it has been a week now and i have no appetite to eat. I do feel hungry now and then but i feel quesy and nauseous when i think of eating. Even the smell of food makes me nauseous. So i have not had a proper meal for a few days and i am quite worried as i am not giving enough nutrition to my body. Anyone else has went through the same?
