When should AI?

[Warrior10]

Pulled cidars/gave Lut yesterday at noon on some heifers, with plans to timed AI Wed night. At 5PM today two had there estrus patches rubbed off, am I correct in that I should AI them in the morning?

I'd breed 12 hours after standing if you saw them. Protocol says 66-72 hours after Lut.

I am going to AI them first thing in morning, because they came into heat early do I need to give them GnRH still?
