Him telling Historia to get pregnant seems at odds with even his current characterization, where he is willing to sacrifice the literal entire world over Historia, his friends, and Paradis. There has to be some kind of twist to this particular point. I still don't believe that Eren Yeager would have ordered Historia to get pregnant. It is not Eren Yeager way of thinking since he's against slaves and cattle.

To me, I think that something have happen like Historia proabaly learned about something and headed towards Eren Yeager. Reason for it because she trusts Eren Yeager and he was the only one who spoken out against her being used as a weapon and breeding tool.

Once they have their private conversation about this, something must've happen in between them. One minute they were talking and then the next, both Eren Yeager & Historia Reiss are making love. That is probably how Historia got pregnant. And the reason why 'Farmer Guy' is involve because he knows of this & willingly to keep it a secret due to feeling guilty.
