I tried to impregnate bandits by raping them, and travelers by rescued reward sex. But after several hours all my attempts failed.
The only way to meet pregnant chara seems to be impregnating girls in the mansion and waiting for the random escape. Girls won't get pregnant until they get captured or recruited into the mansion.
Pregnancy process counts would stop keep going when pregnant girls are in the wild. But they can't give birth until they get captured or recruited into the mansion again.
Selling a pregnant slave to the slaver's guild would cancel the pregnancy process, even if buy her back instantly. Only lactation remains.
And I also found a bug. Sometimes a runaway chara can be recruited repeatly.
If you didn't go back and keep exploring after recruiting a runaway chara in an encounter, you might possibly meet her again in another encounter. Then if you recruit her sucessful again, you would get a same chara occupying another mansion space.

I checked the functions and found out how to get wild chara pregnant
Open this file
mods\AricsExpansion\customScripts\expansion.gd
and edit func dailyNPCs
add a line of code: nightly_womb(npc)
Then npc can get pregnant corretly.
And edit this line
elif npcs[NPC_ACTION] == "childbirth":
change elif to if
Then npc can get pregnant corretly
Add a line of code: npc.preg.offspring_count += 1
to the func npcChildbirth(npc)
