I don't think pregnancy will happen anytime soon due to the fact that there is so much story left to tell. To do a pregnancy segue with how things are in 0.18.1 really wouldn't feel appropriate given each character's current situation. I asked about pregnancy recently and was told "We'll see when we get there." I suspect you will get the same response. As for the Android, she sort of has a child with.... herself? The Android doesn't have a womb; therefore, she cannot have children....and also because she's an android.
