I got positive opks on cd15 and 16 so how many dpo am I at cd23? Trying to work out when I can realistically poas?

I don't use opks so I'm not 100% sure but my understanding is that you ovulate around 24 hours after your lh surge. So if your surge was cd15-16, you probably ovulated cd16-17 so at cd23 you are 6-7dpo. I think!
