I have been on depo for a little more than 2 years and have never had a period until yesterday is it normal that im bleeding again? Also i have been reading and people say after 2 years on the shot you can get osteoporosis and have bone loss is that true? Also i read about infertility and that scares me what is everyone's experience with that? Also one more thing does depo cause ovarian cysts? Im really scared im only 18 any information helps
