I was told on February 10 2009 from a ultrasound that i 7 weeks and 5 days pregnant. That made my due date September 24 2009. so when did conceive?

Based on your ultrasound results from February 10, 2009, which indicated you were 7 weeks and 5 days pregnant, you likely conceived around November 26, 2008. This calculation assumes a typical 40-week pregnancy, with the first day of your last menstrual period (LMP) being the starting point. It is important to note that conception dates can vary and are not always exact, as they depend on individual variations and the specific timing of ovulation. If you have any concerns or questions, it is always best to consult with your healthcare provider for personalized advice and guidance.
