What causes sudden hearing loss with periods and abdominal pain?

I experience sudden hearing loss and vision loss when I have sudden menstrual cramps (Dysmenorrhea). This also happens when I experience abdominal pain related to diarrhea or constipation, which sometimes happens right before my period starts. Sometimes the GI system and the uterus are both affected at the same time.

When I lose my hearing, all I hear is ringing, and everything turns bright, unless Im in a dark hallway. Indoors, I cant see. I think my pupils dilate and the blood flow to my ears constricts. What causes this?
