Already ovulated: You are correct. If your OPK is positive on Friday you will ovulate on Saturday. You will waste time and money on Monday. The reason: The OPK is positive near the peak of the LH surge. A woman ovulates 24 hours after the LH surge. It would of been more appropriate to do the IUI on Friday. Sperm lasts 3-4 days in the reproductive tract. Good luck.
