I Recently changed from wicked whims to wonderful whims. My sims wont get pregnant and I've notice that my MCC setting of risky and try for baby percentage is set to 0 when using this mod. I really want to use it but I don't know I am to fix this.
Don't use birth control measures, and make sure your Sims are at their fertile days when they WooHoo. Unless you've got some other mods' settings change how pregnancy works it should work!
