getting overwhelmed at 5 days late!

I just don't understand what's going on! Tested BFN yesterday but AF still missing.. I'm literally never late or nausea... I'm starting to get a little bummed that I'm not testing positive 🙁 it's really hard seeing all the BFP at 7/ 8dpo and I'm sitting here confused and late 💔 my cm is starting to get heavy so I feel like I'm checking all day because it feels AF is here and still nothing... Day five of being late and I just wish I could see a line even if it's a faint one
