Is it possible to be spotting two or three weeks before your period?

Patient: I had light pink spotting, I thought I was coming on period later that night the spotting was gone. 3 days after that the light pink spotting came back but only for an hour. Next day I took a pregnancy came back negative. Now it’s 2 weeks later and no sign of period very sore breast and moody. What could this be?
