Pregnancy, babies, kids, Batuu question {Pregnancy and babies part: Solved}

Does someone have an answer to this yet? My Sim married a Batuu Citizen and tried for baby, stayed on Batuu a few more days, never got pregnant, and now when she goes back they can't try for baby anymore.

The story is somewhat that she goes back home and tells everyone about her husband from another planet, but of course no one believes her and someday I would like to have the child go back to batuu to meet the father.
