around July 26 I thought AF was coming on but when I went to the bathroom at work I saw brown discharge on pad, (Like you would at the end of your period). Wednesday morning I wake up and see ok there is AF. but then it got light brown discharge the rest of the week. this never me happened to me before. I have read the brown discharge can be implantation bleeding. I have taken two pregnancy tests and came back negative, i have sore and swollen boobs and sensitive nipples, eating constantly. headaches more often then normal, and tired a bit. I'm tring to wait til i see if I get my period this month....its so hard waiting. please I would be like to be pregnant.
