Pregnancy Timeline Calculator for Fiction

Estimate conception, due-date and broad birth-planning periods for story continuity. This is a fiction-planning aid, not medical advice.

Use estimates as continuity warnings, not rigid rules

The full workspace can link the mother, confirmed or possible fathers, pregnancy discovery, expected birth, actual birth and one or more children. It can flag a date that appears unusually early or late while allowing the author to mark the situation as intentional.
