Sex on day period due

My husband and I have been ttc for #1 for 7 months now. My period was due today but it hasn't showed up (14dpo). We had sex (completely spur of the moment!) and normally when we do close to when my period is due, I end up bleeding during intercourse or shortly after. This time round, I had tons of creamy CM.. Like TMI, his thing was covered in it! Has that happened to anyone?? Even he was shocked and asked if we could possibly be pregnant. I took a test at 11dpo and it was negative. Waiting for missed period before I do another one. Really hoping this is a good sign!!
