I was supposed to start my period this past monday. I did not and on tuesday i spoted a little and now i have brown discharge like after a period. I do not use birth control, but me and boyfriend always use condoms and he always stops before hes done and takes it out and finishes. I took a home test and it was negative. My periods are irregular, and i have been under alot of stress lately. Could this just be because of stress? Or do you think i could be pregnant even though the test was negative?
