Ambiguity

Consider the following exchange between a woman with a humorous disposition and her not-so-humorous partner.

Punny Woman: I am pregnant.

Terrified Man: What?! Are you kidding me?!

Punny Woman: Yes.


Given Punny Woman does not pun all the time, is she pregnant?

Slapstick comments are welcome. :)
