Hi, I started my depo shot in February of last year and got it in may, I didn t get it again until September but was not pregnant. That was the last time I got it, I have had unprotected sex and starting a month-month and a half ago my breasts and nipples are extremely tender, I occasionally have hot flashes and get very dizzy and nauseated randomly and starting yesterday I have been having this brown gooey/goopy mucus looking discharge but only when I wipe, not when I pee. Is my body preparing to have a period or should I take a pregnancy test?
