However, you should try to figure out the date of your last menstrual period, since this is the most accurate way to know when your due date will be.Why do we figure out due dates from the date of last menstrual period?It is also around 280 days from your last menstrual period, if you want to figure it that way.But, what if you don’t know the first day of your last menstrual period? You can try to figure out your due date from the date that you think you conceived, if you know that date.
This is an alternate way to figure out your due date if you don’t know the first day of your last menstrual period.
A recent article explained that doctors are now going to be using first trimester ultrasounds to determine due date in the majority of pregnancies.
Earlier this week the American College of Obstetricians and Gynecologists (ACOG) met with the American Institute of Ultrasound in Medicine and the Society for Maternal-Fetal Medicine to set new guidelines for due date determination. James Goldberg, vice chair of ACOG’s committee on obstetric practice, stated, “Some studies suggest up to 40 percent of pregnancies would have dates changed based on [a] first trimester ultrasound.” This difference is because most women do not know the day they conceive and the 40 week rule-of-thumb is based on a 28 day cycle, which is not always a good guideline for women with irregular or longer cycles.
It seems like there are just too many other variables that make figuring due dates out any other way harder and more difficult to chart.
However, keep in mind that your due date is never set in stone.
