First IUI . Question about how many dpo I am

BE

I had taken my trigger on 8/14 and my <a href="https://glowing.com/glow-fertility-program">IUI</a> was scheduled the next day on 15th. I already tested out the trigger today. Today I am 9dpt and 8dpiui how many dpo would you say I am? I got my peak on 8/15. The day of the actual trigger.

Do you think I’m actually 6 or 7 dpo?

My HCG test are ready negative
