The female body naturally secretes lubrication but it could depend on how aroused you were. Sweat is another possibility. It would be a little bit too early for most physical signs and some girls don't even have physical signs before their first missed period. I would consider going to the store and looking at the boxes of pregnancy tests to see when they recommend for their usage and the accuracy related to early usage. Most are most accurate after the due date of the period.

Stress can affect your period, but I have never heard of pot affecting your period. I would wait till you miss your period before spending money on a test as if the condom didn't have any noticeable holes, it's unlikely you are pregnant.
