Dpo question. Input please.

Do you start counting dpo from the day after your first positive opk? Like say you get your first positive opk on monday. And then another positive on tuesday. And then Wednesday is negative. So Wednesday is your actual ovulation day. So on thursday are you 3 dpo or are you 1 dpo? Cause I got my peak on the 2nd. And I got another positive on the morning of the 3rd. Then a negative the afternoon of the 3rd. Had alot of left side cramping that night. So I know I ovulated some time between the negative opk and this morning. So how many dpo would you consider me?
