What the heck is going on here? I was supposed to get my period last Thursday and it still hasn't shown up. I took three test throughout the last week and they were all negative, no faint lines or nothing. I had a friend that didn't have a pregnancy test show a positive untill three months! Which is seems just crazy to me, anyone have any ideas of what could be going on here??!
