The vacation is supposed to be 7 days long; I think I read that at the beginning.
So far, however, there's no indication of a pregnancy, and if she were pregnant, the father, according to the current storyline, would be Doug, since he's the only one who penetrates Rafa vaginally, although he ejaculates outside her vagina.
Therefore, a pregnancy is currently unlikely.
However, I found the clue about the mirrored surface next to the TV during Movie Night.
Rafa and Bruce have anal sex on the NTR path there, which could explain the cum flowing out of Rafas ass that Doug finds at the end.

And as for Stacy, during Movie Night on the NTR, she doesn't let Bruce touch her anymore, while Erick only gets a handjob/blowjob from Rafa.
They're writing about what Doug can read.
In this conversation, Erick reveals that he invited Stacy over and that Stacy doesn't want to have sex with him because she's in love with Doug again.

I still think that Doug and Rafa might break up or even get divorced in the end on the NTR path.
Doug could actually get back together with Stacy in the epilogue or a part 2. Rafa would presumably be Bruce and Erick's playtoy for a while, and if Bruce and Erick finds another slut, Rafa could try to win Jim over, or she could end up with Trevor. Who knows how that will turn out? It could be a few years before we know...
