What week pregnant are you considered when you get a BFP?

I got mine this morning and am confused how far along I’m considered.

I got a positive OPK on Dec 11, but didn’t actually ovulate until either dec 14 or 15 (confirmed by blood work with my fertility specialist).

I was basing my DPO on dec 14, so technically I’m 11DPO. I started seeing a very faint line on 8DPO and this morning I took a digital test that said Pregnant (pic below).

So how far along am I considered??
