I Had A Pap Smear And A Vaginal Ultrasound Last

I had a pap smear and a vaginal ultrasound last Tuesday and the doctor recommended a D&C. On Wednesday while I was at the hospital for pre-registration I started to feel ill. By the time I came home I had to throw out. I have had muscle aches, starting with pain under my arm, chills, fatigue, nausea, occasional headache and dizziness. I had a flu shot but could I have the flu. Should I delay my surgery if I not better by Monday. The surgery is scheduled for December 14.
