I have been getting depo shots since the beginning of this year and recently have found out that the side effects can be long term and very painful (which I now have). also that the shot even makes it harder for you to get pregnant when you are trying to conceive. That could take up to 3-18 months! This is just my experience. But my family and I are very heart broken by this. Please ask you doctor about the birth control they prescribe you.
