Even with the debug, you can accelerate the pregnancy, but only up to 28 week.
You actually give birth around week 35 or so.
That means you have to skip manually around 35 days.
And you can do that only on debug in the bedroom, by double clicking then clicking on the same button over and over again.
Again, not the most practical. I'm pretty sure this game could be coded equally by having a multi option menu for each places instead of having to navigate your map to get to the room you want.
