Help!!! Dpo?

Claudia

Ok so I’m not understanding the whole dpo and how to calculate it and everything. So my last period I had was 05/29/2020. But we didn’t have sex until after my ovulation on the 11 of this month and I’m in my ovulation time now. And I’ve taken a few test and idk if my eyes are seeing things and my brain is tricking me and me getting my hopes up.

These were Thursday

These are yesterday

I have been trying for four years now to have a baby and been thru a couple of miscarriages I just need some help cause I don’t want to tell my family or friends until I know for sure.
