From what I learned in Nursing school, every method of birth control has a lot of side effects due to hormones. I would talk to the health department tomorrow and talk to them about how badly your breast hurt because any severe pain is not normal. I had the Depo shot twice before I stopped it all together because it was messing with my blood pressure due to me being a smoker. Other than that, I had no problems with it, however everyones' body is going to react differently, and as much as I hate reading this and I am about to say it... you will need to talk to the doctor who gave you the shot. I wish I could help you out more, but since everyones' reactions are different and I don't have your health history in front of me I can't!! Just know that pain is your body's defense to let you know something is wrong, so if your pain is that severe I would urge you to call in the morning! I hope you get well soon!
