Testing out the trigger shot?

So this is my first IUI cycle and I have been testing out the trigger shot. I see a lot of people say it can be out of your system anywhere from 4-14 days afterwards. Is there a difference in IUI success rates dependent on how many days it takes for the trigger shot hormones to be out of your system? Like would it be more likely to have a successful outcome (bfp) if it takes closer to the 14 days, or maybe closer to the 4 days? Or if that even a factor in success rates?

My brain keeps coming up with ridiculous questions while I wait for our blood pregnancy test in 2 weeks. 😅
