Does any of the naruto girl's ever get pregnant?

Technically,yes.

Kurenai Yuhi, the Jonin sensei in charge of Hinata,Kiba,and Shino's team does.

She becomes pregnant with Asuma (Ino,Shikamaru, and Choji's sensei) and her child in Shippuden.

However Asuma never finds out because he dies before Kurenai got the chance to tell him :(
