My cervix hurt. I don t know what s going on? Also I seem to have vaginal discharge of a white thick substance that has a foul odor. I ve been on depo birth control for a month now (on going two), I m sexually active but the last time I had sex was Monday, I took a test this month (stds, HIV, etc.) and I was found clean, I don t think I m pregnant because some of the symptoms don t occur to me (morning sickness, swollen breast, large breast, headache, etc). I don t know whats going on! and I m very upset. Am I pregnant? Am I infected? Is it just part of the birth control? Etc. How can I stop this cramp feelinG in my cervix and having discharge? Its unpleasent. Am I allowed to douche or would that harm me? ( I read somewhere online that it can wash off the good bacteria and etc)
