Abnormal period with normal results

I am at a loss. I have gone to multiple GYN’s trying to find answers. My periods have gotten worse and worse as time passes. My right lower side hurt so so bad during ovulation and a week before my period/on my period. I have had MRIs and a CT scan to check for appendix issues and everything was normal. Drs said the pain is too low for it to be that. All my bloodwork is normal. I have hair growing on my face like a man, and I am so emotional all the time. Crying, angry outbursts, depression, you name it. I have had an ultrasound done, internal and abdominal, and my new GYN said there are some cysts but it’s normal. He said he doesn’t know what too do. He said he doesn’t recommend birth control pills since I’ve taken it before and it caused me to have gallbladder issues, high cholesterol, and it didn’t help my mood swings. I don’t know what to do. My mother had endometriosis and PCOS. I can’t keep spending money on drs appointments to be told “I don’t know what’s wrong sorry”. Has anyone else gone through this? I don’t have any friends that have gone through this and I feel completely alone and at a loss on what I can do.
