Yeah, the pregnancy is really making me think worse of Beverley because I cannot imagine it being accidental. The Rivers strike me as being in at least subconscious control of their own embodiment to a very great extent; I don't see how Beverley could get, or at least stay, pregnant inadvertantly.

And given that she didn't TELL Peter that they were engendering a new genius loci via the aforesaid spectacularly unsafe sex until after the fact, I think her pregnancy is another reproductive decision she's made unilaterally.

I'm a lot angrier on Peter's behalf than I think Peter is ever going to be, though.
