The mod allows reproduction for NPCs, from mating to childbirth, adding menstrual cycles for the women NPCs met in the game and, in case of sixual intercourse during the fertile period, there are chances for a pregnancy to start.
This mod is a resource for other applications, using only the main module.

The management of menstrual cycles is divided into three phases:
- the follicular phase
- the ovulation
- the luteal phase

If there is sperm during the ovulation period, there are chances for the woman to be fertilized. If there is several sperms from different males, the future father is drawn.

A fertilized ovum is likely to become an embryo but can also die within 5 days.

Pregnancy is declared five days after the end of ovulation phase.

Pregnancy is divided into phases and ends with the delivery between the 85th and 95th day.

I'm on FDBB v2, restarting from scratch to optimize and securise the code. This version will be definitly a modder's ressource and only the engine to manage women cycles and pregnancy.

I plan to built on side, or help to built, gameplay mods based on, like some for inseminating women or manage the birth and childs, they will be in other threads nammed like 'FDBB - what you like'.

The new version of engine,will be released in beta before the end of year, and would have these fonctionnalities :
- 400 women can be referenced
- if female, player will be the first woman referenced
- cycle length will be configurable
- sperm life will be configurable
- fertility will be configurable
- foetus may die during pregnancy
- by default, pregnancies will be announced
- by default, births will be announced
- by default, child won't be referenced
- by default, referenced women may be pregnant from other NPCs if some are near during the nights

Optionnaly (in order of priority), the beta version will have these fonctionnalities
- by default, women apparence may change during pregnancy
- by default, pregnancies will be stored in quest journal
- by default, births will be stored in quest journal
- multiple fertilisation will be possible with the same father or differents fathers

This will be version 1.99.xxx in beta stage and version 2.0 on release. I'll need beta testers to reduce the beta stage.

On the next step I plan :
- add interfacing with other mods capable to inseminate women (with or without animation, can be through dialogues). Romance modders, contact me please
- add interfacing with other mods capable to get the birth event and manage the baby creation

On the next step I plan to develop my own mods to manage insemination and birth if no other solution.

sorry for my bad english
