sim won't get pregnant

Hi @93b0e1cdc3088821b862abc61a1e69c5 !  I'm sorry you're having trouble with pregnancy in your game.  Maybe start by checking a few things.  First, check that one sim is able to become pregnant while the other is able to get others pregnant.  You'll have to take both sims into CAS and click the three-dot menu below the gender signs.  These are the custom gender settings and if they don't have the right settings, you'd have to use the cas.fulleditmode cheat to change existing sims.  If those settings are correct, next check that your sims have at least half the romance bar towards each other.  The last thing to check is to see if the sims have had their "first kiss".  It might sound odd but I've experienced this before where my sims didn't have the "try for baby" option until they had the "first kiss".  I hope this helps.
