Help!

Flashing smiley face 3 days in a row starting from 7DPO, any thoughts as to why ? Only tested because I got told they couldn’t see evidence of ovulation on my ultrasound, so thought maybe I’m ovulating later so decided to test, however the next day I got my bloods back with a very high 40 progesterone level indicating ovulation has indeed occurred. Any thoughts as to why I’m getting this?
