Adds a menstrual cycle to the women of Skyrim for role play purposes. Tracked women proceed through the menstrual cycle and can become pregnant as well as give birth to babies and Hearthfire-compatible children.

Requirements

SKSE

SkyUI (for MCM configuration)

Installation/Removal

To install, add the mod with your favorite mod manager (recommended), or drop the extracted contents of the archive to your Skyrim Special Edition Data folder. You may be prompted to overwrite UILIB, it is safe to do so.

To uninstall, remove the mod with your favorite mod manager (recommended), or delete the archive files from the Skyrim Special Edition Data folder. It is recommended to leave UILIB as removing it could break other mods that utilize the library.

How Does It Work?

When Fertility Mode is enabled, women encountered within Skyrim will be automatically tracked. Insemination can be achieved automatically with an MCM option, through additional mods such as Flower Girls or SexLab, or by using the debug MCM menu when the woman is selected in your crosshairs. Additionally, when married, sleeping with your spouse will also inseminate one or the other accordingly.

After being added to the tracking list, a woman is given a random day within the menstrual cycle. The cycles will be updated in game time (every hour by default), and when the end of the cycle is reached, it will start over back at the beginning. The cycle is partially realistic, with a menstruation phase (no chance of pregnancy), an ovulation phase (good chance of pregnancy), and a luteal phase (low chance of pregnancy).

Three craftable potions are offered. One for increased fertility, one for reduced fertility, and one to terminate an existing pregnancy. All of these can be crafted at any cook pot.

If the conception checks succeed, the woman will become pregnant and the cycle will be paused for the duration of the pregnancy. During pregnancy, the woman will experience belly and breast growth at a uniform rate. At the end of the pregnancy, birth options will be applied, then the cycle begins again after a recovery period. Birth options include a wearable baby in a sling, a filled black soul gem, and nothing. If the baby item is selected, the player's children will potentially grow into Hearthfire-compatible children.

Both male and female players are supported. As a female player, you have a menstrual cycle and an informative widget showing your current state. As a male player, you are included in automatic insemination and can explicitly inseminate women through Flower Girls or SexLab. While pregnant, the player must sleep regularly, as the baby's health will gradually drop.

Children

Babies can grow into child actors. This only occurs if certain requirements are met:

The player must own at least one Hearthfire-compatible house.

The player's current home must have at least one free child's bed.

The player must not have reached the Hearthfire adoption limit (2 in vanilla, 6 with the Hearthfire Multiple Adoptions mod).

The player must not be in their home at the time of spawning.

The mother's race must have a supported actor (all of the vanilla races are supported).

Both male and female players are supported, and the race of the child will match the race of the mother.
