Questioni am 27 and am currently pregnant with my first child. The first day of my last period was approximately 13th October 2005 which would have given me a due date of 20th July 2006, but when i had my scan they gave the date of 31st July 2006, i need to know when i would have conceived the earliest or the latest possible, or even an exact date would be great!
AnswerIf you have a 28 day cycle (from the first day of your period until the first day of your next period) ovulation occurs on cycle day #14. You can conceive if you have sex on cycle day #13, 14, 15, ro 16. If your last period started on October 13, ovulation probably occurred on October 26 and you couod have become pregnant if you had ses on October 25,26,27, or 28. Your due date is July 20. Depending on when you had the scan, there is an error in the sonogram.If you had the sonogram at around 20 weeks gestation, there is an error of + or - 14 days.
