Customizable length randomness ranging from 0% all the way to 99%! Though, 99% means some unlucky sim will be pregnant for a very long time. + Some pregnancies will last a little longer than normal, others will last a little shorter. This mod is inspired by a mod for TS3 with the same name, and it adds just a little bit of realism. Add some variance to your sims' pregnancies with this mod right here folks.
