Somethin' I noticed with my OCD need to find order and evenness: Going from when a girl gets pregnant, to when she can get pregnant -again-, is three sets of fourteen weeks, in the default form. (Pregnant again being four weeks after birth). After another -four- sets of fourteen weeks from there, your child is fully grown and is either sold (sons) or added to your dungeon (daughters). Fourteen is the magic number in childbirth. Seven sets of fourteen weeks from impregnation to 'of age'. Just thought I'd share that.
