i have been using depo for family planning for 3 mnths then it expired,then i changed to the pill but ionly took it for 1day and stopped because we decided ti have another child,so for the past 3mnths now i havent seen my periods and at times am neaseas ,there is water coming out of my breast and i have started to have back pains and in my stomach,i have tested more than 4 times with a test kit and it says negative and since yesterday am seeing dark mucus like discharge but not too much though.Does this mean am pregnant?
