Question 1

How is the conception date estimated?

Accepted Answer

Conception typically occurs around 14 days after the start of the last menstrual period (LMP) for a 28-day cycle. Working backwards from the due date (280 days from LMP), the estimated conception date is approximately the due date minus 266 days.

Question 2

Can I know my exact conception date?

Accepted Answer

It is generally not possible to pinpoint an exact conception date since sperm can survive for up to 5 days and fertilization can occur within 12–24 hours of ovulation. The conception window typically spans 5–7 days around ovulation.

Question 3

How does cycle length affect the conception estimate?

Accepted Answer

Longer cycles delay ovulation, which shifts the estimated conception date later. For cycles longer than 28 days, add the extra days to the standard estimate. This calculator adjusts the conception window based on your reported cycle length.
