Just a Little Curious.. and JFF

I found out at 18 weeks with each of mine, just a normal ultrasound, though I did have the 3D ultrasound done also (with my second pregnancy). They just got a new 3D machine in the office, and I had complications and had many ultrasounds. Since I was in the office all the time anyway, they did a couple of the 3D ultrasounds - very cool! When I found out the sex it was with the normal ultrasound, though.

i think 20 weeks is the norm; that's when i found out too. any earlier and it can be hard to tell, which is why most doc's don't like to say earlier.

I heard about the Chinese lunar calendar it said I was having a girl. I had my dr's appt later that week dr said it was a girl.
We did the 3d/4d (paid for it ourselves) it's more detailed we could see she had hair, her entire face... we even ck'd to see if she was a girl (again lol)
I thought she looked like me.. She came out looking like her dad!!

I found out both my little ones were boys at 20 weeks.
My friend just had the 4D ultrasound and found out she was having a boy at 14 weeks, this was confirmed at her 18 week ultrasound.

20 weeks, and it was just a normal ultrasound, not 3D or 4D.

I knew I was having a son as soon as I first heard his heartbeat lol. And sure enough at 20 weeks I had an ultra sound and the doctor told me there were "extra parts" so I was definately having a boy!

I didn't do any u/s checking for the sex and back then, there weren't 3D and 4D. I didn't have just for fun ultrasounds. With my 2nd baby, the only u/s I had was the one to guide the amnio needle at 14 weeks. With my first, I found out the sex somewhere in the early 20's of weeks. I had first decided I did not want to know but after a scare I did - but I used the amnio results and not an u/s for that. With the second, I didn't find out beforehand

My OB told me between 18 and 20 weeks is the best time to start. He said that the genitals are fully formed by then. My next appointment is on May 11th which I will be in my 18th week and we are going to schedule the sono then. I didn't find out with my first but with the 2nd I want to know. I am very anxious to find out this time. Can't wait! 3D and 4D ultrasounds are usually not covered by insurance so the 2D is just fine with me. Hopefully the baby cooperates so we can find out!

Don't know about the dimensions, however, I found out our son's gender at the 20 week ultrasound.

With my first I found out at 20 weeks. My second was 18 weeks. My third (and more recent) was at 16 weeks. My current pregnancy was at 14 weeks. I found a 3D place in my city that would guarantee what they saw at 14 weeks. I have to say, I could easily tell as well. It was verified by my ultrasound by my OB's office at 18 weeks.

I found the following about the difference between the ultrasounds. Don't know how accurate it is.....

2D ultrasounds are the traditional black & white ultrasounds you have probably seen before. The pictures show the skeletal structure (outline) of the baby. You also get to see the baby moving! This is the type of ultrasound that was probably used for your diagnostic ultrasound. It is still the best technology for gathering measurements of the baby and ensuring that the baby is developing as expected.

3D shows the tissue of the baby, which is more like real pictures. We can see the roundness of the baby's face, the shape of the nose and the contours of the lips. The color is actually not the color of the baby, it is computer enhanced to make the pictures more appealing. We can show the baby in sepia, blue, green, or red.

4D live is the same technology. With this technology you can see the motion of the baby. Some companies call it 3D Live and some call it 4D Live. If your baby has a large, clear pocket of amniotic fluid around the face, is moving about and is developed enough, then we can get great clips of motion (4D live). The 4D live clips are typically only a few minutes.

I just knew that when I saw my baby on the first ultrasound that it was a boy. I was so relieved that there was a baby since I preiously miscarried. at the 20 week ultrasound they confirmed that it was a boy. Sometimes you just know.
