Positive OPK the day after IUI

Helena

I had my very first <a href="https://glowing.com/glow-fertility-program">IUI</a> done yesterday morning CD 15 6/8 @9:30am. Trigger shot 6/7 @7:00am.

Out of curiosity, I took an OPK test at home today @3:00pm(56 hours post trigger shot/30 hours post <a href="https://glowing.com/glow-fertility-program">IUI</a>) and it turned out positive.

I think the trigger shot should make me ovulate within 48 hrs, but it’s been 56 hours.

Could anyone tell me does it mean I haven’t ovulated yet? Or is it caused by the trigger shot?
