DPO Question

Kandace • Sat, Jul 20

So I got a positive opk on CD17, I'm pretty sure I ovulated that same day. I had tested 2 days before that and got a negative so I'm not sure if maybe CD16 was my peak or CD17 was my peak. When I tested on CD18 it was a faint line. So how many DPO would I be? 2 or 3?
