Hi, all I have a ? I calculated my cycle right and my doctor is saying my due date is dec 10th 2009, but I think he is wrong. My last cycle was feb 25th 2009 that would make my due date dec 2nd 2009, he said he was going by the ultrasound could it be wrong I went off my cycle on march 2nd 2009.

But I didn't have a cycle on march 5th 2009, if I did then my due date would be dec 10th.

Well... I am still in my first trimester and had my 11 week ultra sound done and the tech said my baby is measuring a week smaller. As she put it, "it just goes to show that not all women ovulate in that 10 - 14 day period." So I had to start my eleventh week over again and my due date had been switched. Maybe that could be why? Just a guess though!

You might be right but my cycle started on feb 25th and went off on march 2nd.
