I have been getting lupron depot injections since my laproscopy back in August and had no trouble the first month except for hot flashes. After the second injection I started to experience migraine type headaches and I would get the shakes really bad through the night almost as if I was coming down with the flu. I just had my third injection and the symptoms are worse. I feel tired, nauseated, body aches, chills through the night and hot flashes all day long. Will my symptoms continue to get worse as I go on? I have two more months of injections and I am contemplating not doing it. My husband and I have a beautiful little girl but really want another child. Is two more months really going to guarantee pregnancy or is it a waste of my time?
