What is causing this pain ?

Im asking this question for my mom. A half hour ago all of a sudden she got a very extreme pain in her ovaries and still has it now. She says that it the pain is constant and feels like Intense labor pains, she had 2 children and it never hurt as much as this. When it first started she was in cold sweat and crying because of the pain. Now she cant move because of the pain and is laying in bed with a heating pad on her trying to relive the pain. She wants to know what is causing this pain, and should she go to emergency room. Also she is in menopause and stopped having periods last month
