Birth Control
"I had nothing but negative effects from the Depo shot that are continuing even after the duration of action of the Depo. I am now experiencing terrible migraines (I rarely, if ever had even minor headaches). They have been occurring multiple times per day including nausea and diarrhea.  I experienced these same symptoms for the first time after I received my first shot. I also experienced neck stiffness, severe mood swings, bouts of depression that seemed to arrive from nowhere, no sex drive what so ever, and worst of all menstrual bleeding for an entire month straight which was only counteracted by a high dosage of birth control pills.
