What exactly was the result of thr premate test? if it was just that ovulation was just starting or about t6o occur then she may well not be ready as far as the dog is concerned.
The eggs are ovulated (usually over a day or two) in an immature styage of developement and cannot be fertilised for a further two days, after which they wil remain viable for a further two days.
If you took her on or the day after ovulation she will stil be OK for another 3 or 4 days, and some males prefer to mate bitches that are really ripe.
