Pregnancy

General information
Pregnancy is an optional kink, which is turned off by default, and must be manually enabled in the Sanctum. It can affect both the player and some characters.

Note that enabling pregnancy, getting pregnant (either yourself, or impregnating the others), and then turning off the pregnancy would not terminate the ongoing pregnancies.

Player's pregnancy
There's a random chance to being impregnated after any scene involving vaginal creampie (assuming Lust Doll has vagina). Exact probability is currently unknown, but a Fertility Pill raises it to 100%; note that one pill ensures one pregnancy, and must be taken again to reapply the effect after giving birth.

When impregnation occurs successfully, the player gets notified about getting Pregnant: Early Stage status effect. The early stage has no inherent effects on its own, but after some time, it progresses into Pregnant: Late Stage, which overwrites it. The late stage directly affects the stats, adds visible belly to character's portrait, and modifies some encounters (see this page for details).

The late stage pregnancy never wears off on its own; the only way to get birth is to visit the Nursery in New Ark.

NPC's pregnancy
Some characters may be impregnated by the player. Unlike the player, those characters requires a Fertility Pill being taken before they can be impregnated, which can be given to them through "gifts" menu; it may be impossible to impregnate them until certain story progression with them gets achieved.

Their pregnancy varies in time needed to develop, with some taking longer than the others. While on late stage, their appearance changes, and additional scenes becomes available.
