Hello, does anyone know if ultrasound
measurement's can be off by 5-7 day's??
My last ultrasound said that I was exactly
9week's when if I got pregnant when I
"know" I did the baby's measurement's
should have been almost 10week's?? Can
baby's be smaller than normal and isn't
every baby different? And does this mean
that my due date could be off by a week?
I am really confused, this is my first.
Do the doctor's go by "exact"
measurement's?? They told me that my last
period was nothing to go by anymore, only
the baby's measurement's would be more
accurate in dating the pregnancy? In my
case my baby is measuring a week smaller
than what it should be? Is this normal??
I am really really confused, does anyone
have any type of help or advice to
offer???

You didn't neccesarily get pregnant that
day you had sex!
Sperm can survive in the uterus for upto
around 5 days, just chilling and hanging
out for the odd egg to pass their way.
So you could have had sex on monday and
gotten pregnant on thursday
hope this helps

Hi.... Posted: 09-05-04 15:08pm
Well I added the 5 day's and it still
dosen't make sense....We were together on
the 9-10th and the ultrasound is showing
time of conception around the 18th..That
means his sperm would have lived 8
day's!!! If I give or take the 5day's
then it would make sense..I noticed on my
ultrasound the at the bottom it said +/- 5
day's, and giving that, conception would
have been around the 14th which would make
sense. I was just worried about the baby
being small for week's pregnant. I am
just un-sure on how to understand
everything, I have read alot of stuff, and
also that sperm can live up to 7-day's!!
I was just wondering about ultrasound's
and them being a little wrong sometimes??
