Okay,well, I had recently started depoo not neccessarily as birth control but to regulate my period. My first shot was in early december and I was due early march. I never went back for my next shot but my "Period" has seemed wierd. Normally I have a very heavy cycle and right now it has been very light and the color went from a light pink to brown. When i would noramlly be using a pad and a tmpon at the same time, im only using a pantyliner. My breasts are very sore and Ive been real achy and moody. Do you think I could be pregnant?
