Other factors (e.g. stress) can result in ovulation being delayed, until as late as the third or fourth week. However, the way our care providers calculate pregnancy due dates is by assuming ovulation on day 14 of a 28 day cycle. You can already see a major reason why due dates aren't so accurate!
If the sperm is too early or late, it cannot form an embryo. Ovulation, which is the release of eggs, typically happens around 12 to 14 days after the first day of a period (or the start of a new cycle). Implantation occurs 6 to 12 days post ovulation. Calculating the ovulation dates, menstrual cycle and implantation can be very confusing.
