What Are The Side Effects Of Ovranette?

Hi, i am a 21 yr old female. I have been to the doctors with sickness and he has given me tablets. However i feel strange, i am on the pill (ovranett) and my doctor said it would be impossible for me to be pregnant. But i feel wierd, sore back, not hungry, and sickness and headaches for around a week, my skin has broke out in spots as well which i never get. My doc thinks it is a bug. I am only a size six and i dont look any different than usual. I have taken two pregnancy tests last week but both are negative. Surely if its a bug i shouldn't still be ill over a week?
