hi, can you add a button in the preference for pregnancy mode?
i... kinda click it and im so far from the beginning...
Changing this setting during a playthrough wouldn't make much sense since it will alter the story with its own chain of events. But it's not that big of a deal; in the current version of the game, this setting doesn't even have an effect yet. Pregnancy is a late game thing. You will proably replay the game anyway when new updates get released.
Otherwise, you can just cheat. Unlock the console as described here, load the save you want to modify, open the console (Shift+O), type
pregnancy = True
then press enter, close the console, overwrite the save you've loaded and you're done.
