I would not get too wound up over that, though. Just have an attempt when it's possible, you're already in with really good attempts.
No, you don't have to have 3 attempts after positive OPK. You should have three in the fertile window. Many people are still hung up on Shettles, and THEY want to wait till pos OPK for the three attempts, but you don't need to do that - 3 in the fertile window is what we're after.
