Hi, I have experienced sort of the same thing. However, DH and I have been TTC. But, I haven't gotten my period and it was due anywhere from 3-10 days ago. But, when I wipe (for the past two-three days, I see a pinkish discharge on the TP. I researched a little about implantation bleeding and although I don't know if that is what I experienced, that could very well be what you experienced. If your period is late already, you can take a HPT. Pulling out isn't 100% effective and so there is a chance that you could be pregnant. Let us know the outcome! Good luck.
