AF 3 days late but I'm only 10DPO. Anyone else??

So I'm on CD33 of my normally 30-31 day cycle. I ovulated even later than usual on CD23 which means I'm only 10DPO. And my luteal phase is around 12 days so I should expect AF by Sunday 10/4.

I've been having lower back aches all week which is usually a sign of AF but it comes almost right away when I get the lower back ache. Also, very mild abdominal cramping off and on.

Tests all week have been BFNs. I ran out of tests and i refuse to buy more till Monday! Good thing its a super busy weekend.

Can anyone else relate????!!! I'd love a cycle buddy or just someone who has had or is having a similar experience.
