IUI SEMEN question

Hubby and I had sex this morning. Then I had RE appointment. They told me I’m having my <a href="https://glowing.com/glow-fertility-program">iui</a> tomorrow and gave me trigger shot. I honestly didn’t think I would have been ready yet. So now I’m worried bc we had sex this morning that his semen tomorrow won’t be as potent. Is this a valid concern or are we ok?
