My period is always regular. It last came on 29 November and should be due on Christmas Day. Tonight for first time ever I experienced very slight bleeding a hour ago. I recently made a move back home from Europe to Latin America after 10 years away and have been busy and stressed I guess. I'm 40 years old with no children. The bleeding seems to have stopped as I write and it was never flowing or heavy. Just streaking and brownish. Should I see a doctor tomorrow?
