So, you had an 8 day period while taking the pill? That's probably unusual. When on the pill, we don't really have periods but more like spotting during the sugar pill part of the pill pack. We are taking the hormone, and then during the sugar pill part, we aren't . . . which induces the bleeding you experience. It would be rare for that to last 8 days. Coming off the pill can cause a shift in hormones and you definitely could be experiencing that. But, to be safe, get a cheap pregnancy test and take it to rule that out. Doubt you are, but never hurts to check. good luck
