[Harry Potter] I just took polyjuice potion of a woman who, as luck would have it, is about to go into labor. Am I now also pregnant? Am I having this kid? Does the kid disappear after the potion wears off?

I would say that you become a version of the woman who *appears to be* pregnant, with all of the discomfort, needs, and shape of such a state. But you just get the experience of what she's going through during the span of time in which you plucked the hair from her head, not necessarily the baby and the eventual birth. 

The kid is a separate entity, so you don't duplicate the kid, but the mom is, shall we say, *in quite a state*, and you get all of the annoyances of that state.
