Hi, I think what they were trying to say was that, if their sims tries for a baby and they're successful than the "take pregnancy test" option will not appear on the toilet, but when they're unsuccessful in conceiving the option for "take pregnancy test" will appear on the toilet.
I think their problem is that the "take pregnancy test" option is disappearing when they successfully try for a baby...
they also noted that the only other script mods they have installed are MCCC and slice of life
*hopefully that made sense :)*
