Due date november 7th?

Hi All.

Good news, it finally happened ! Cant wait, but one thing I am confused about...I am due November 12th according to mybabybirthdate.

LMP was 1st of February, so conception shortly after? Is this correct or do you use a more accurate method to determine the due date?

Suggestions welcome! thanks a lot

They date you from the first day of your last period as opposed to the actual day of conception. So for example if you conceived on 14th february and tested positive two weeks later on 28th february TECHNICALLY you are only two weeks but they will OFFICIALLY class you as being 4 weeks pregnant. It's just the way it's done!
Hope this helps and congratulations.
