Your due date, or estimated date of delivery (EDD), is the
estimated calendar date when your baby will be born.Because prenatal tests and fetal development
are affected by your due date, having an accurate date is important.
How does a doctor determine your due date?Your healthcare provider can give an
estimated due date based on your last period or by performing an early
When determining your due date, your healthcare provider
will need to know the first day of your last menstrual period (LMP).Based on the first day of your last menstrual
cycle, your due date will be 280 days away!
If you are unsure of the first date of your last menstrual
period or you have irregular periods, an early ultrasound will be the next best
tool for obtaining an accurate due date.Because of the timing of fetal development, early ultrasounds are the
most accurate at determining a precise due date.As pregnancy progresses, ultrasounds are not
as reliable at determining accurate due dates.
Doctors don’t generally use the date of conception as an
accurate reference for pregnancy dating purposes.You might think that you know exactly when
you conceived based on the timing of sexual intercourse, but fertilization may
not have taken place exactly at that time.Sperm can survive in the uterus for three days, allowing conception to
take place anytime during intercourse and up to three days after.Based on the date of conception (if it could
be pin-pointed), your due date will be 266 days later.
Based on ultrasounds, fetal growth, uterine development and
other factors, your due date could be changed during your pregnancy.Due dates are only an estimation of when your
baby is expected to be fully developed and ready for birth.Your baby could come before, on or even after
your due date.Research shows that less
than 5% of babies arrive on their actual due date, so don’t expect your little
one to make his/her grand appearance on the EDD that your caregiver
provides.Most babies will be born
within 2 weeks of their estimated due date.

SO, mt LMP was on 25MAR2011 . and I do not know my average cycle length, tends to be longer I think bc I was on the DEPO shot a year ago.... I THINK
CONCEPTION date was 16APR2011
which means I would be about 11w3d and EDD of 1/6/2012
my first ultrasound said I was 12w1d and EDD of 1/1/2012
based on my LMP I would be 12w3d and EDD of 12/30/2011
I know its not a diff of very many days (6) but Is this all accurate??

when i went for a u/s at 11w6d, they said i was 11w3d... then the u/s at 19w2d they said i was 18w1d... i've been confused ever since! but i read somewhere that the dating at 18wks isn't as accurate as earlier (like my 11wks one) so i'm gonna stick to that, the baby will come whenever he/she feels like :D

So according to my ultrasounds, I am one week further ahead than I should be. According to my period, I should be 19 weeks, but my ultrasounds are showing 20 weeks. I thought today at my appointment, the doctor would say I was 19w5d, but he said I was 20w6d. Apparently my baby is a big baby for how far I am along. Anyone else have an issue with being confused about how far along they actually are??
