These optional extensions are part of the updates, and they are as follows – Sims using protection (wicked whims or MCC) reduce the chances of pregnancy to 0.5%. If you use 0% with another alternative, then 0% chances would be at the top, and no pregnancies would happen. The 15% – 100% chances are void if you more than one.
Even if they are on their periods (wicked whims) or are already pregnant, this alternative would work. 0% chance – this option would indispose the chances of getting pregnant for all ages.
