Just to add more reassurance for you I have had exactly the same, and in the last year, although I have had no period since February, I have had two bouts of PMT like symptoms in April and June which did make me think I was about to start bleeding.I am hoping to finally make it to February as I am a ripe old age, but certainly PMT but no period has happened to me over the years, including some episodes that were so severe that I thought it would start any moment but then the feelings faded overnight.I have also heard ladies say the same who have had maybe a spot or two of bleeding with the PMT but then nothing more for several more weeks until the feelings built again. I have several friends who say their last period ever was PMT and only a spot of pink or 1/2 day bleeding.
