12 DPO and losing my mind!

Wanna see if anyone else is in the same boat.

12 DPO

CD 30

AF due tomorrow

No spotting

Terrible lower back pain

AF like cramps for 2-3 days that i can feel a twinge in my ovaries every now and then

BFN on DPO 8,9,10,11

Didn't test yet today, going to test in the morning.

Thoughts?
