My six week u/s was january 4. when did i conceive?

~12/7/12: That answer is only accurate if your 6wk ultrasound actually occurred at 6wk0d. Enter your data into http://www.Babymed.Com/pregnancy-calendar-and-calculator-week-by-week which also gives due date of 8/30/13. Entering 12/7/13 into http://www.Perinatology.Com/calculators/due-date.Htm also gives same due date so you've got 2 different online calculators pointing at about same time. Congrats!
