A free mod for Mount & Blade II: Bannerlord, by SquidyBallinx.

This application allows you to control the chances of pregnancy and birth. It offers two sets of options: one for you and one for your partner.

For you, it allows you to speak to your spouse about the frequency of your sexual activity. If you both choose the same setting, it will raise the chances of pregnancy.

For your partner, it allows you to make choices depending on the rumors you have heard in the world. If you choose to pursue these, you will have the opportunity to use them.

This application has been tested only by myself and there are already known bugs.
