Do all fetuses grow at the same rate in the first trimester?

Customer Question

Do all fetuses grow at the same rate in the first trimester? For example, could an 11 week fetus be mistaken for a 7-8 weeks fetus, just be slower at growing?

Dr. Owen :

Hello, I am Dr Owen, I am a Board Certified Ob/Gyn Medical Doctor and I want to help you.

Dr. Owen :

Hello

Dr. Owen :

All fetus' grow at the same rate but could be off by as much as 8%

Dr. Owen :

So an 11 week ultrasound would NEVER be mistaken for a 7 to 8 week fetus -

Dr. Owen :

so there is no way that would be possible.

Dr. Owen :

I hope that helps

Dr. Owen :

If you have more questions, please ask

Dr. Owen :

Thank you

Dr. Owen :

Dr Owen

Dr. Owen :

So to explain what 8% means -

Dr. Owen :

an 11 week fetus could be off by as much as about 6 days

Dr. Owen :

a 7 week fetus could be off by as much as 4 days

Dr. Owen :

So you can see you can NEVER mistake an 11 week fetus for a 7 week fetus.

Dr. Owen :

I hope that helps

Customer:

How accurate would an abdominal ultrasound be at 7 weeks? I had an abdominal ultrasound (I am thin so they said it would be ok), but it didn't line up with LMP, so I was just wondering if it could be off.

Dr. Owen :

If the abdominal can measure a 7 week fetus it is JUST as accurate as the vaginal - the measurements of the machine are the exact same.

Dr. Owen :

Honestly we really do not take into consideration LMP when doing an Ultrasond.

Dr. Owen :

and there is No possible way a 7 week measurement no matter how it is done can be confused with an 11 week ultrasound - it is absolutely impossible.

Dr. Owen :

and since you had a 7 week ultrasound - that is the ultrasound that is used -

Dr. Owen :

for dating

Customer:

ok thank you!

Dr. Owen :

You are welcome

Baby has cheek dimples, but neither her father or I do. How is this possible? True that baby can't have dimples if parents don't?
Expert:  Dr. Owen replied 9 months ago.
Dimples on babies honestly are not necessarily genetic.

So people can look very different from their parents and siblings.

For example I'll use me as an example - NONE of my brothers and sisters look alike and NONE of us look anything look like any of our parents.

So it is possible to be different.

I hope this helps

Is it true that you can tell future skin color from cuticles/ear color? When do most mixed babies get their skin color? When does true eye color set in?

Expert:  Dr. Owen replied 9 months ago.
you can NOT tell skin color from the cuticules / ear color...

Usually by about 24 hours - the color of the baby will be what it is.

And, eye color - you really will not have TRUE eye color until about 4 to 6 months later.

I hope this helps
