How far into cycle does Egg retrieval usually happen? IVF

t123
I know it depends on our follicles etc, I usually had my IUI's anywhere from the 14-17 of the month. Is it usually the same timing or is it sooner/further down the month? 
Reason I ask, is because it should take 14 days from the time I order my donor sperm again to get here, and I'm not sure if that'll be enough time before the hospital needs the samples... (I will be asking my doctor come Monday but they are closed and I'm flustered) My cycle usually starts 3-4-5-6 of the month ... So I'm just not finding the timeline example I'm needing online thanks y'all
