How long will I have to wait to know if pregnant?

Destiny

Okay, so me and my fiancé had recently made love together. And we know he came inside me. So how long will I have to wait to know if I am pregnant or not? We are currently not trying to get pregnant so I don’t know about taking my birth control because if I am pregnant then I don’t want to hurt the baby in anyway, even if we wasn’t trying to conceive. We aren’t ready to have a baby yet because of some stuff going on in our personal lives but it’s besides the point. We both know what we were doing and we are able to take responsibility for it if I do end up pregnant. So how long will we have to wait for me to try a pregnancy test or to know for sure if I am pregnant or not?
