Suggest Treatment For Stomach Pain And Vaginal Discharge

Hi, I was wondering if you could help me. I have been experiencing extreme period pain, particularly right before I get my periods. It's to the point where i cannot move or do anything to get rid of it. i have never been able to sit it out and always end up taking neurofen. I seem to have a low libido atm. i don't know if this has anything to do with it. i thought i had thrush as i had a white cloudy discharge, a week ago and took medication for it (the tablet you insert into cervix). I still have the white cloudy discharge today. There's no smell. And it's not itchy. I get pains in my stomach area before i need to go to the toilet (not when i need to urinate). I also have extreme mood swings. Go from such extreme highs to lows. Could this have something to do with my hormones? I have a history of abnormal cells, and have hpv, but haven't seen any signs in 5 years. Can you help?
