How to track DPO?

It’s our first month TTC and I’m wondering how other women track their ovulation and dpo?

Do you mark ovulation as the same day that you get a positive opk? Do you mark it as the day before your temp rises? Do you mark it as the first day of EWCM? All three of these vary for me... I got my positive opk on CD 15, a small temp rise today on CD 17 (wondering if it will rise a little more tomorrow), and EWCM on CD 14, 15 and 16...

I’m wondering if today (CD 17) I’m probably 1 dpo, 2 dpo or 3 dpo...? 🤷🏼‍♀️

Any tips would be greatly appreciated! My cycle varies by a few days every month so I want to make sure I don’t test too early
