So I have been on depo for 10 months now n just recently I have been feeling very sick to my stomach, not hardly eating or sometimes over eating, extreme fatigue, very moody and having colostrum leaking out. I have an 11 month old daughter but I am beginning to think I'm pregnant again. It feels like it but my test came up negative. My question is.. how effective is the depo? ( I also am not getting any periods on depo)
