Well...: If your due date is accurate, you most likely conceived from an ovulation date around december 6, with the intercourse that led to conception being 5 days before to 2 days after that date. Now. Even early ultrasounds are not always 100% right on the date. There might a 4-5 day error margin either way. So it is not inconceivable that you might've conceived in the last few days of november.

Five Days: The standard answer is that sperm live up to five days after emission. So the closest they can come to is a five day window around conception.
