I don't know the DPO because I'm still not sure when I ovulated. I have a 26 day cycle and I believe I ovulated sometime between CD 11 and CD 17, lol. I know that's not helpful. I saw "spots" of pink, so faint I couldn't be sure on the first day of my missed AF, CD 26. Saw a faint line at 3:30 am the next morning, one day after missed AF.
