A little over 3yrs ago after I had my son I had my tubes tied. Every since my cycle has lasted longer, my cramps are very painful, and my mood is very bad during that time. Nothing over the counter has helped. Before I had my son I found out my pituitary gland is about 3X the size it should be. My question is, has anyone had this type of change after having that surgery? And does it sound like my pituitary gland may have something to do with the change?
