About the Conception Calculator
This calculator estimates when conception likely occurred. From an LMP, conception is estimated around 14 days later (at ovulation); from a due date, it is about 266 days earlier. Actual conception depends on your individual cycle and ovulation timing, so treat this as an approximation.
