How can I reasure my husband....

I had almost that same problem... The doc kept writing down Dec. 21 when I know it was Jan 4... it bothered me so bad becuase my husband was visiting his family on the other side of the country for the month of dec... I finally confronted my doctor about it and he said that they use the date of your last period becuase it is a solid date unlike when you conceived which can be hard to pinpointed... I felt so bad because the paperwork says it happened when my husband was gone the best thing to do sit down and talk to him and reassure him of your faithfulness that's what I did and I made me and him feel alot better about the situation... Best of luck

once they are able to preform an ultra sound they will measure the baby and may find a more accurate date. The due dates are always a quick estimate and Doctors will do everything they can to ensure you and your babies saftey. If you really feel strongly about it, be sure to emphasize how sure you are to your doctor so he can really help.

Jessandmike is right.  They go off your last period, cause it's a concrete date.  when they do an ultra sound they will measure the baby and dates can change.  I was also a preschedualed c-section, but we didn't scheual it untill we knew when the official due date was, which was around 24 weeks (I ended up having placenta abrasion and needed an emergancy csection about a week before hand anyway).  I wouldn't worry about the dates at all.  My sister when she was pregnant they had no idea how far along she was nor when she was due, her belly was saying one date but the baby said another.  My niece was 3 weeks overdue.  Good luck.
