Are pregnancy calculators right or sometimes wrong?

The pregnancy calculators online are 100 percent correct and work the same as the ones the OB use -- as long as you know for sure the exact first day of the woman's last menstrual period. 

You can't use the date that she found out she was pregnant as a starting point on the calculator. Think about it. Some women find out 7 days after ovulation and some find out when they are already 4 months pregnant. 

If you don't know the first day of the LMP, the OB needs to use other methods of dating the pregnancy, which are less accurate, such as very early ultrasound measurements.
