Both vets were right. If the result is in nanograms per ml, then Monday was the LH surge, as it is the day before the progesterone goes approximately above 1.9-2. So Monday was Day 1. The best breeding days are usually days 5 & 6 (Friday & Saturday), with the next best being 4 & 7.(Thursday & Sunday). Better to error on the early side than the late, as sperm can live over a week if conditions are good, so Thursday is an ok choice to start. So you would have caught the bitch with either the Thursday and Saturday or the Friday and Saturday breedings. As long as you bred by Saturday, you should be fine, and even a Sunday breeding might have caught her. In normal circumstances, it only takes one correctly timed breeding -- I have done only one breeding and ended up with seven puppies. The other breedings are just for insurance that you've caught the right time, in case there is some problem with sperm longevity.
As an aside, I will tell you that some vets recommend doing another progesterone a few days later, to make sure that she proceeded to ovulation (about 5ng/ml), but a normal bitch will usually always proceed to ovulation once the LH surge takes place. A bitch with an inadequate surge may take longer, or not proceed at all. I don't bother getting a second one after it is above 2, but I might if it was a bitch with fertility problems. The other nice thing about knowing the LH surge is that it generally tells you your due date. Counting the LH surge as day one, the due date should be on day 65; it rarely varies more than a day on way or the other. Knowing this can save you some sleepless nights.
