Hello, im very concerned because I had my tubal ligation done in 07 it wasn't the normal procedure it was this thing called a clamp which is total new to me, after my 3rd child and now it is 2011 and I finally have sex with my other and he thinks its ok to be free an ejeculate inside me after almost 4yrs. Now im experiencing symptons of pregnancy like lower back pains lower abdominal pains tenderness in my breast and even nauseusness. I going crazy cuz these are the same signs with my3 other children. Is it possible for me to be pregnant.
