abnormal uterine bleeding
"I have had the first shot of depo and I bleed for 2 months strait I went to the gyno and they had to get the layer of decayed uterin wall and the gyno advised me not get on the depo shot anymore because he's had to many women come in with the same problem. So I would advise get the rod in your arm it's strictly progestin just like depo but you don't have any bleeding at all"
