2 days late, BFNs, light spotting this AM now nothing?!

Help girls! Anyone been in a similar situation and got a BFP later on? I'm 2 days late and my cycles are 28 days long EVERY MONTH. More discharge than usual and very painful boobs. Keep thinking af will show but she doesn't! When wiping this morning, I had the lightest light pink tinge to my discharge but absolutely nothing since. No period cramps either! Is this a good sign?! I did see that someone didn't get their BFP until 7 days late! Xx
