So, I been on the depot shot sense October first time taking it in about a year or so. Well, I haven't had sex sense December. Come January, my vagina became real itchy and irritated when I wore my panties. I had sex! And the day after I had a light brown discharge. The next day I noticed an evn lighter discharge. Wasn't as thick, but I experience my vagina having a weird feeling. Pulsating in my stomach and pelvis. I took a pregnancy test before the dp. Idk.. help
