Not stupid IMO. Some girls are locked out of pregnancy even with EFPs, and/or first birth, until specific events happen.Stupid question, but before I keep start save scumming, Gwynneth just had her child and yadda yadda questline led to the threesome with Victoria. Is it possible to get her pregnant again during this scene or only if she has the house?
I haven't seen an instance where once a girl has her first pregnancy and first birth she requires special circumstances to knock her up again, regardless of where you do the deed. Try it and let us know how it goes.
