pregnancy question

This has me curious, and it might be a stupid question, but is it possible to be pregnant if I were to have sex two, maybe three times during the week that I'm supposedly "fertile"? Also, not letting the cum marinate in me, but instead peeing after having sex? If my question makes sense? Any stories of becoming pregnant after having a few days of sex and not letting cum sit inside you for 10+ mins? Lol 😣
