Hi there ~
It is unclear from your history as to what the condition might be. I am thinking that if the pain is coming from your abdomen and you are having regular bowel movements
and urination as well as all sexual functions are normal, you might need to get an ultrasound
of your abdomen and pelvis done. I strongly suggest that you visit with a surgeon to have yourself checked out and have some labs run on you. I hope this helps to relieve your anxiety
Take care and have a lovely day !
