Anyone IUI 24hour after trigger? And TWW buddy? IUI is on Dec 21st

Ladies, did anyone ever have trigger shot and 24 hours later IUI? I thought the IUI is approximately 36 hrs after trigger.

Anyways since this is going to be our last IUI doctor wants to be aggressive. He wants me to inject one more time tonight and trigger tomorrow morning and IUI on Thursday morning. I’m worried I would not be ovulated that early but at the same time I’m worried I ovulate before then, because I’m having a lot of EWCM. The nurse said don’t depend only on IUI, do lots of intercourse too. Hello, my husband is 40 with full time job. He’s not a teenager! Lol 😂
