Hey.
Did you change any settings?
Do you have other mods that might affect how pregnancy works?
Did you run the game with only WonderfulWhims?
How and What do I change in setting? and i dont think i have any other mods installed the would conflict with this, unless mccc affects it
So I take it you didn't change settings at all?
Did you try taking the test with a different Sim to see if it works?
