Today 1dpo or tomorrow?

Kloe

I’m definitely new to the whole <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a>. And I’m aware that the position only indicates a surge in LH and within 48 hours I could ovulate I think. But since I got positive tests yesterday (05/06) and today (05/07), would today be 1dpo or tomorrow?
