cecilia silva answered question 5/31/2007 What Can Cause Very Painful Contraction Like Pains In Lower Abdomin When Not Pregnant Or On Period? Should I Be Concerned If They Only Come Once Or Twice A Week Or Just Ignore It? My sister has had pain and she has to get her left overy taken out this week to stop the pain. I suggest that you contact a obgyn as soon as possible.
