Pls help! IUI 4 days ago took an opk test just to see if I'm still ovulating

So my <a href="">IUI</a> was 4 days ago and we did an ultrasound and follicle check. The size of my follicle and the blood test showed that I was getting ready to ovulate and didn't need trigger cause my doctor said it'll happen within 24 hrs. So we did

<a href="">IUI</a> the same day. I'm now 4 days past

<a href="">IUI</a> and out of curiosity I took an opk test just to see what it'll look like. Now I'm confused, did I actually ovulate when my RE told me which was 24 hrs after my

<a href="">IUI</a>? Or am I still ovulating?
