Right timing for IUI

I'm a bit nervous about the timing of my <a href="https://glowing.com/glow-fertility-program">iui</a>. I was scheduled to have it done on the day after my first pos opk (natural lh surge/no trigger shot) but it got pushed back to two days after due to miscommunication with the dr office. RE says everything should be fine. Looking at my chart he maybe right, but I'm unsure..

may I have some feedback pls?
