IUI/LH Surge

Just came back from the doctors with my wife for our first IUI in office.Last night we inseminated at home, today in her office using IUI, and have another IUI scheduled for Friday.I tested this morning and had high fertility using my clear blue digital test and also wondflo opk but no LH surge detected.When we got home, I held my pee for like 3 hours then took these same tests again.We got positives this time for ovulation and I am over the moon.Our next IUI is Friday but is that to late? Should we just do an ICI at home tomorrow?
