Weird "period"?

Dee
  I had light bleeding for 2 days on the scheduled day of my period to start then...it stopped! No usual PMS symptoms or a week long of heavy flow. I'm afraid to test..tired of seeing BFN. I tested on the 16th of the month-it was negative...bleeding started 2days later. Anyone ever had an unusual "period" (or bleeding) and still got their BFP?
