Pelvic inflammatory disease

Elisabeth
Hello,
Has anyone every experienced PID? I was having bad pains in my lower right side. After being examined my dr said I could have PID. She took an std test which came up clear; since PID can be caused from untreated chlamydia. I was given a shot and antibiotics just incase. After a few days the pain stopped but the pills where making me really ill. Therefore I stopped taking them. 
Has anyone else ever had a similar experience? Any advice?
