I am a little concerned. My period is due tomorrow (11/28/12), and I started spotting 5 days ago. When I say spotting I mean not bright red blood, but just pink stuff, which then went straight to brown. Not enough to fill a small panty liner but enough for me to notice. My breast were tender a few days before this happened, so I assumed I was having an early period. However, the cramping got more intense (like my usual mid-period, heavy bleeding stage of my cycle) but I never bled normally. Since then, the spotting has stopped and yet my breast and nipples especially are very tender, I am having hot flashes and no more cramps. Did I have a period? Or could I possibly be pregnant? Also, I am not on any birth control and my boyfriend and I did have unprotected sex throughout the month.
