Sims can’t get pregnant

[Stephanie619]

For some reason none of my sims can get pregnant. I use whicked whims and have them try vagina sex and finish but they can’t even take a pregnancy test. When I enabled cheats and shift clicked the sim, it said under the whicked whims pregnancy info “can get pregnant: false (75%)” 75 percent is what I have playable characters set to for pregnancy chance, and I double checked in CAS that “can get pregnant” is checked. So ??? What does the false mean?

Do you have the menstrual cycle feature enabled? If so, "false" means that Biology tells you "not today".

Does your "target" Sim use any means of birth control? If so...well, it works.

Do you have pregnancy enabled in WW's settings? If not, there'll never be any pregnancy, even with a chance of 100%.

 

In any case, have you tried the vanilla "Try for Baby" interactions? I always use those, when I want a sim to get pregnant (and then MCCC if I want to influence the number and gender of the children), because they only take into account two factors - "Sim can get pregnant" and a static chance for pregnancy.
