Chances of EDD being off by a good bit?

My Dh and I were discussing this. I am not talking about how your dr gives
you a due date, and you could go into labor before or after it......I am
wondering what the chances are of an EDD being way off due to inaccurate
dating of the pregnancy etc. I know ultrasound is unreliable as to the size
of the baby does this mean the machine could date wrong too?

Here is why I ask. LMP was August 8, but it wasn't a normal period I told
the drs about it but they are counting it as my LMP....it really only lasted
like a day and was very light. Mine normally are 3-4 days. I am wondering
could I have already been pregnant at this time and be a month further along
than they think?

Don't laugh Dh and I can't help but wonder, because of all the pressure I
am feeling in my pelvis etc. I know we can't second guess it also just
because my stomach is huge, either. I am not being hopeful etc and I was
never planning on having her until within 2 weeks AFTER my EDD of May 17.
But I have had the strangest feeling here lately, that even if my EDD is
right, I have the strongest feeling that I am going to go early. (again, I
can't explain this feeling! It's not wishful thinking and I actually have
always planned on having her later than my DD, and to think of her coming
early would throw me off-- I feel unready!).....I'm not *afraid* of having
her early, either,,,,,but it's the strangest, strangest feeling....like a
premonition. I was just one day doing something and I stopped and said
"Oh.........she's going to come early!".............if I turn out to be
wrong, I'll eat my words and forever be confused as to why I feel this way,
since it's not wishful thinking etc....it's more like of a warning feeling
to myself....

But I have been wondering if there is any chance the drs could be wrong
about my EDD due to the LMP, since that is what they base it on.....it
wasn't a typical period for me.

I doubt an ultrasound could be off by a whole month. What was the EDD based
on your ultrasound?

I'm fairly certain that my edd (based on ultrsound) was about 1 week early.
I'm not sure as much as a month though. The dating scan was at week 12.

Possible. But probably not if you had an early dating scan.

I was convinced dd#1 would be induced 2 weeks late: Result-3 days late by
LMP (and based on a 28 day cycle and mine are 35-42days)
I was eaqually convinced dd#2 would be early: Result-4 days early by
(apparent) ultrasound guess.
Try and unconvince yourself! Make sure you're ready (as I was with #1) but
the wait with #2 seemed never ending, and she really felt late by the time
she arrived. The wait was very stress inducing.

But I have been wondering if there is any chance the drs could be wrong
about my EDD due to the LMP, since that is what they base it on.....it

LMP date: could be. Are you measuring large? not that that's necessarily
anything to go by-my fundal height was about 6cm short by the end)

Late-term ultrasound is unreliable for estimating the size; before
about 13 or 14 weeks, though, it's pretty accurate. When was your
ultrasound?

My friend was in a similar situation, a light period. Whe she went for her
ultrasound at 12 weeks it turned out she was a month further along. If you
had an early ultrasound it should have picked it up if you are a month out.
Further along the ultrasound is not so acurate for dating.

As for the feelings of pressure and braxton hicks etc.. I had both from
about twenty weeks. I was very uncomfortable and went to 41 weeks first time
and 39 the second. I had two ten pound plus babies. I know that's probably
the last thing you want to hear. On the upside I did have easy labors. I
think all those Braxton Hicks were doing something from early on.

If you were a month further along I imagine you would be measuring at least
a few weeks ahead on fundal measurements but I'm no expert!

Why?

if I turn out to be wrong, I'll eat my words and forever be confused as to why I feel this way,
I don't think all of these dramatics are at all necessary or even
worth considering -- I would just chalk it up to hormones or the fact
that it's your first pregnancy and you don't really know what to
expect. My EDD is May 14th and I measured between 1&2 weeks bigger
than they originally thought and they did a US to be sure and when I
was at 28 weeks they said the baby looked to be about 29 weeks but my
EDD hasn't changed.

I don't understand. You say you know that ultrasound is unreliable, and
you ask if this means "the machine" could date wrong too. What are you
talking about?? The "machine?" Which machine? The ultrasound machine? Some
other machine? I'm confused.

Certainly it is possible that you had non-menstrual bleeding August 8th
and were already pregnant at that time, in the absence of any evidence to
the contrary. That being said, it may be the case that there IS evidence
to the contrary that I don't know about...

When was your first ultrasound? I would wonder if, when you had your
earliest ultrasound done, the measurements made sense with an LMP date of
8/8 or not. Also if the development of the fetus was at the appropriate
stage...

Why?

Probably because a term pregnancy is anywhere from 37-42 weeks long and it's
easier to get through the last few weeks if you imagine you won't give birth
before that 42 week mark.

My LMP was Aug 12th, and i'm due on May 21st, BUT if i count the weeks
on the calandar I am only about 29 weeks not 30...BUT ive been counting
the weeks since the 14th day AFTER my LMP..and that is Aug 25th so that
is when I THOUGHT i got pregnant, because i always heard it was 14 days
after the first day of your period that you get pregnant...
Oh. then I saw in a magazine that you add 7 days to your LMP and add 9
months THAT is your due date, and that leaves me at may
19th...omg...this is so confusing...

If your LMP was only one day, my guess is that you were already
pregnant...and didnt know it...
If i were you I would have your bag packed...;-)))

I'm packing mine soon too, even though i dont think i'll go too early,
but i think i will go a little early....;-)

and i dont want my DH in charge of packing my bag...lol....
