Hi! I used depo provera as a form of birth control May 2014 & quit the shot in March 2015. It has been 4 months and I'm having the worst headaches imaginable, cramps, no period, cranky, nauseated, blue veins in my breasts, montegomery glands, symptoms similar to pregnancy but I took 4 tests which all came out negative. Am I pregnant or suffering from the shot? I'm going crazy. :(
