Are they saying Jan 7 because of a sonogram that was done? This is not unusual for the dates to change slightly. They are looking at the size of the fetus right now. I know people who knew the day that they conceived and even their dates changed by sonogram. Based on when your period started you would be due on Jan 20, 2009. You most likely conceived between April 19 and April 23, most likely around the 22nd. By conception date you would be due between Jan 6th to Jan 10th. Which is right in line with your sonogram. Pregnancies are not really based on 9 months, but 40 weeks. I hope this helps, Good luck. Susu
