What CD do you ladies get your surge?

We've been super busy with stuff this month, so I've been slacking on tracking & BDing. I'm on CD 17 with a 34ish day cycle. I had a dye stealer on CD 16 last month, but this month I've only tested on CD 8, one in between somewhere, & then two today with none a positive surge yet. do we think I'm out or maybe just surging past CD 17 this time?

When do you all get your surge & how long are your cycles?
