How many DPO?

Good afternoon everyone!

So I’m TTC. I’m confused about when I ovulated though.

On April 24th, I had a static smiley on a clear blue digital. According to the test, this is 12-24 hours from ovulation. My strips (Pregmate and easy@home) were negative. By the 26th my Pregmate was a blazing positive. By 27th my Easy@Home was “peak”.

Anyone know what dpo I would be? I had inseminations the 24th, 25th, 26th, and 27th.
