Determining the exact date of conception can be challenging. Generally, it's estimated based on the first day of your last menstrual period (LMP) or by counting 11-21 days from the beginning of your cycle if it's regular. For more accuracy, ultrasound scans within the first trimester can provide a closer approximation. However, an exact date is rarely pinpointed unless conception occurred from a single known instance of unprotected intercourse.
