abnormal uterine bleeding
"I first started Depo-Provera due to irregular and heavy menstruation. The first month was the worst, with several side effects that did go away after the second shot. I had severe breast tenderness, with some lymph node swelling, mood swings, and constant spotting for the first month. After the inital shot, I never had a period again, barely any spotting, and felt well. I did go off the shot for a while and now I am on it again. I am having no side effects except for the initial moodiness and decrease interest in sex. But I would still recommend this product for someone! No periods - Sign me up."
