Uh-Oh

So Monday I had sex with my best friend of years like we're talking 11 years of friendship and he said it was time to see if we had a connection sexually, so there we go to have it and of course he says "I have no condom do you" obviously I don't cause if I knew this was happening I would of brought some! Anyway claiming his pullout game was strong it was weak as all hell and long story short is if he did ejaculate in me how long should I wait to take a pregnancy test?
