Help?

My af was due today so far no sign my cervixs is extremely high I can just about touch it with the tip of my finger and it appears closed. I've had increased cm too and I'm very moody sounds mad but my four year old seems to be really hard work at the minute and I don't no if that's just me or he is sensing a change other then me being the big bad wolf lol. And ways I let glow no I'm late and insted of it saying take a test or some sort of pregnancy advice it just pushed my af to the 8th witch has also effected my ovulation date. What does this mean?
