    Yes, go by the first day of a missed period, if they have an irregular period then an ultrasound can also help to determine how far along a woman is.

    With our son, we first used the Last Menstrual Period to determine. Then we went in for our first ultrasound around 10 weeks-we thought based on LMP that I was 13 weeks-but the scan revealed that I was only 10 weeks along. They remeasured him at my next ultrasound at 21 weeks and it was right on track from the first ultrasound.

    I've heard that the first ultrasound is the most accurate.

    Yourself or a friend? If yourself, go to http://www.babycenter.com/calculators/duedate/ and enter the first day of your last period and it will tell you how far along you are. If you don't know then you will have to find out by going to your doctor so they can do ultrasound. Good luck!

    Ultrasound is the best way; otherwise they do go by the first day of your last period.

    Yep, ultrasound.

    Technitions will measure the baby's head circumfrence, abdomen circumfrence and femer length and compare it to a chart... that'll give you your approximate gestational age. The earlier the ultrasound the more accurate it'll be.
