14dpo and expecting AF today, but no cramping today and so far no blood at all?

Today I'm at 14dpo. I've been starting exactly every 28 days. EXACTLY. Every 4 weeks, on Sundays. I had some cramping last night, but not as bad as I normally do with AF. And now, this morning, I have nothing. I had cramping, bloating and pressure 5-8dpo then it all stopped. I haven't had any spotting or anything. I know I'll just have to wait through the day, but I'm nervous and want to know if there's hope. My nipples have been hurting really bad for about 5 days now, and I've been getting mild waves of nausea. I've also been really tired. Yesterday, I woke up 10am, laid back down at 4pm and woke back up at 6pm, then went to bed for the night at 9pm. I don't do that, ever. So, any advice would be appreciated. I've been posting questions on here for a couple times this cycle--I'm just so nervous and excited. Please help me!! Thanks!
