When did you conceive if your due date is November 4?

To determine when you conceived, count back 38 weeks (266 days) from November 4. This calculation assumes that pregnancy lasts for an average of 40 weeks, with the last two weeks considered overdue. Subtracting 266 days from November 4 indicates that conception likely occurred around February 15. However, it's worth noting that the exact date of conception can vary due to individual differences and irregular menstrual cycles.
