Possible signs?

AF is supposed to start this week, fingers crossed she doesn't show her face! She's due today and hasn't made her presence known so hopefully that's a sign.

However, I'm having incredible nipple sensitivity. We did do the BD yesterday where that was an area of focus, but not for long. They have been hard most of the day and I am more aware of them than I normally am, if that makes sense. Is this a potential sign or am I being hopeful?
