White discharge abdominal & pelvic pain.

I am unmarried 28 years having relationship. I have white discharge and itching from last December. I took fungal tablet no improvement. Suddenly I got abdomen and pelvic pain. Last 2 weeks before I took antibiotics I felt good for a week after my course. After my periods again started getting white discharge abdominal and pelvic pain. I did urine routine blood CBC all normal . I did trans vaginal scan the Impression is bilateral overian cysts with internal echoes - ? Endometriotic. I did abdomen scan and found stone in my kidney the size is 4mm . Vaginal swap test normal. Waiting for pap smear and urine culture test results. Doc told me I may or may not have endometriosis but it's not confirmed . Bcz of kidney stone I am getting pain so she asked me to drink more water. Someone tell me what are the possible cause for these symptoms. Will that be a PID? Or endometriosis? Or something big. I am scarring a lot. Is there anyway to find out the real reason for this symptoms?
