I thought the affects of salive on sperm were mainly regarding low sperm counts and motility? The saliva did not actual kill the sperm in any significant amount.
We would need a bit more information that than. How long ago was your last period? How soon after your last period did you test? It's not common for women to get symptoms of pregnancy two days after their last period. It takes more time than that for them to show up.
