I have been feeling Nausea,tired, frequent urination , bloating ,lower back pain, brown string-like discharge, food cravings , weight gain & headaches. I had my tubes tied after my second kid. And I get the Depro Shot due to the fact I was having really bad issues with my menstrual periods. It is almost 2 years that I have been on depro. Need to know what it could be. Thank-You
