Can you have more than one autoimmune diseases at the same time? - autoimmune more condition_symptoms

I have trouble to find a true diagnosis of my doctors. This is item 4 I see a doctor in a year. He said he had fibromaialgia accompanied by other symptoms of lupus (rash, alopecia, positive ANA sacroilical 80) and neck problems that may indicate Ankyliosing spindolitis. It was really great and create a panel of blood tests and MRI scans, the results of X-rays of my sacroiliac joint.II suppose to confirm it again. However, I wonder if it is possible to have three diseases at once. Does anyone know?
