<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been feeling really sick lately. I have nausea and vomiting, and Ive noticed a strange vaginal discharge. I also feel pain in my lower abdomen and experience intermenstrual bleeding. What could be wrong with me?  <response>: Based on your symptoms, its possible that you may have Pelvic Inflammatory Disease PID. Its an infection in the female reproductive organs that can cause nausea, vomiting, vaginal discharge, suprapubic pain, and abnormal bleeding. Id like to run some tests to confirm the diagnosis and start treatment as soon as possible.
