Conception timing: Conception occurs around the time of ovulation and is about how many days after the start of the LMP?

Explanation:
Conception happens when the egg and sperm meet around the time of ovulation. In a typical 28-day menstrual cycle, ovulation occurs about two weeks after the first day of the last period, so conception is usually around day 14 after the LMP. Sperm can live several days and the egg remains viable for about a day, placing the fertilization window near this midpoint. If cycles are longer or shorter, the exact day shifts, but day 14 is the standard estimate for a 28-day cycle. The other options don’t match when ovulation and fertilization commonly occur in relation to the start of the last menstrual period.
