Hey guys! I was suppose to get my period on October 17th and It's the 21st now. I'm never late!! I mean ever!! I have taken 5, yes 5 pregnancy tests but they have all been negative. (I even took one today) Has anyone ever taken a pregnancy test after their missed period that has come out negative when they were really pregnant after all?? I don't know why else my period would be lat because I'm not stressed, haven't had any eating or excercise changes, etc... Someone help me please!!
