So after a one time pink spotting two days ago (CD 28) and then a few drops of red blood first thing yesterday morning (CD 29) when I went to the loo, AF never actually showed. And no more spotting today, either at least so far. My temp dropped a lot today though. I'm so confused about what is going on with me right now???
