The answer to your question is yes, she can very well have
taken. The eggs need two days to ripen, after ovulation, before they
can be fertilized. And, the eggs then can live for two-three days, even four, before they are
too old. There is a chance you'll get more male pups, than females, though.
On day 19 of her season, it's far, far too early to get any sympthoms of pregnancy.
The nausea will set in, if it does at all, about three weeks after the mating. That's when the eggs
fixate to the wall of the uterus.
Any signs of not being well this early, are not normal. There is always
the risk of infection, and if in any doubt, I'd take her to the vet for a check up.
Good luck with your upcoming litter,
Karen
