My boyfriend came in me for the first time

So today I was extremely drunk. My boyfriend and I went out to the river well after we left we went and had sex on a dirt road in the back of his truck ( I said yes so it's OK) anyways it was so passionate and sexy the best sex we've ever had and he came in me for the first time ever (I told him to) I want to have a family with him and I really hope it will happen soon. (: when is the soonest I can take a pregnancy test.. And I never have a regular period so IDk when I would have a "missed period"
