I decided to take the depo shot last year in march of 08' and only took it once for and ever since I started taking it until this day on I'm having menstrual like cramps. my gyno said that im fine and to take some ibprofeun. and she had me start taking birth control pills to help ease the cramping but never did it once help it actually made it worse. do you think anything could be possibly wrong because I even called the depo 1 800 number and they couldn't even figure out what was wrong with me.
