Her trigger is during the visit to the woods with her and Rachel. While you sit on a bench you'll get a conversation about kids. Also, giving her a creampie after that is mandatory of course.
but i did that and nothing i chosed that i want to be the one and then she catched me with rachel and the u know what happens maybe i can find a wolktrough on ph bcuz even if i really love this game its too long :)))
i rwerite this i did choose the oprion adn creampie her it said that she was pregnant but then on th 139 day when i checked she was no longer pregnant its a difference if shes is not pregnant?
