13 DPO Am I out?

Hi everyone,

Got a shadow on a few tests but nothing to truly affirm anything. Anyone get a BFP this late? No sign of AF. I think I’m 13DPO, not 12.

Posting chart. I had some twinges on and off at 10-11dpo. I have had waves of nausea random (lasting 1/5 minutes) since Tuesday. My boobs feel bigger and tender.

My cousin never got a positive hpt with her second, is that common? I’m unsure how long my LP actually is. 3rd cycle after iud removal.

Cycle 1 - period 11dpo

Cycle 2 - chemical pregnancy, period 16dpo (positive tests 11-15)

Cycle 3 - 12/13 dpo no sign of AF and no affirmative solid lines

Am I grasping at straws here? Thanks!
