Conception is defined as the inception of pregnancy, or the exact moment when an egg is fertilized.
Women who conceive using in-vitro fertilization (IVF) or other assisted reproductive technology will have other information from the procedures to figure out their date of conception.
The calculator assumes that ovulation occurs 14 days before your next expected period, no matter the length of your cycle.
It only works if your cycle lengths are 21 to 38 days long.
These calculations are based on the average period of conception for a woman based on either the First Day of the Last Menstrual Period or the Predicted Due Date as provided by a health care provider.
The Early Gender Test depends on accurate calculations.
