Ok here is my breakdown ,12-20-09 started my period , 12-22-09 started BC b/c I read you can start while on period . 12-24-09 BC was misplaced by child taken from my nightstand so I started a new pack (different brand) on 12-25 / 12-26-09 . 12-30-09 fiance and I had unprotected sex , he came inside 2x that night . 1-5-10 began spotting brown discharge/blood , it happened all day was gone @ night . Woke up 1-6-10 to a little blood which I thought was my period ( due this sunday according to BC ) but I took tampon out a few hours later and only a bit of brown again ? Light cramping . I am confused I keep hearing of implantation bleeding , what do you guys think . Please give me some input .

Thanks xox
