abnormal uterine bleeding
"I have been receiving the Depo shot since July 2013. This has been my first and only birth control I've taken and a huge benefit is that I am not worrying about taking a pill. However, for the past 6 months I have experienced spotting. It is not enough blood to need to wear a tampon, however it is very dark blood which stains underwear. This has been extremely frustrating to me and I am now trying to decide what will be my next best option of birth control will be."
