They could just be ovulation cramps. I usually get pains near my ovaries a few days before ovulation. Since you are a cycle day12 that would be my guess. I have a friend that gets the pains real bad. You could always go and buy a ovulation predictor test and see if that is what it is. Hope this is helpful.
I have an appt on June 2 because I have not been able to get pregnant, so I will ask about it then.
i had this for years everytime AF arrived or was near i would be laid up on the sofa for 2 days i found out a few weeks ago that i had adhesions in my tubes, my right tube was twisted and i had mild endometriosis. I don't think you would have any of these if you'd had a child but i would get it checked out i know how unpleasant it can be good luck
