Baby Boy Ultrasound At 12 Weeks

How can one predict baby gender from ultrasound report at 12 weeks?

Depends on variables: Although the parts may be present it is difficult to be accurate on gender assessment at 12 weeks.In the hands of a skilled tech with a high resolution probe this can sometimes be suggestive.However, it is more reliable around 18-20 wks. Even then, I have seen folks who decorated a nursery based on us have to repaint when baby delivered. ...Read more
Sonogram (Definition)
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

If i am 14 weeks pregnant will my baby measure at 12 weeks or 14 weeks based on ultrasound.

Same thing, 14 weeks: if your pregnancy is dated correctly from your last menstrual period, and if the ultrasound is also interpreted correctly they will both say 14 weeks. You do not adjust the ultrasound for the 2 "extra" weeks from the last menstrual period. ...Read more

How accurate is ultrasound done at 18 weeks pregnancy in determining baby gender if baby cooperate. Gyn saif 100% boy. Can he still be mistaken?

8 weeks pregnant ultrasound showed 4 weeks.fetal pole n yolk sac not seen gestation sac seen is everything alright?its my first baby

Most likely, YES: Ultrasound is superior to your period in dating early pregnancy. A gestational sac is the first sonographic sign of pregnancy and appears about 4 1/2 weeks. Next is the yolk sac at about 5 weeks. The fetal pole with a heart beat at about 5 1/2 to 6 weeks. So, yes, it appears your pregnancy is progressing normally. ...Read more

20weeks 4days pregnant. US showed baby weighs 1lb 2oz and measuring at 22weeks. LMP on point so no way he's older. Will he be a big baby?
Too early to say!: at 20 weeks how large a baby will be. I wouldn't worry too much at this point, the estimated weights are just that - estimates - and the baby has another 20 +/- weeks to go. Likewise with EGA (dates) - 2nd trimester ultrasound is generally considered within +/- 2 weeks, so your 22 weeks and 20w4d overlap. Good wishes. ...Read more

Diagnosed my baby fetal macrsomia. I'm 33wks+5 and fundal height measuring 37 wks. Ultrasound at 2 wks ahead. Have no risk factors. Should I worry?

Macrosomia: Every baby grows at slightly different rates. U/S measurements are "dated" on an average growth rate, so any given time may be larger or smaller than average, but still be normal. Sometimes, the U/S may be correct, but since bleeding can occur with pregnancy, you may just have gotten pregnant a month earlier than you calculated. ...Read more

10 weeks transvaginal ultrasound baby heartbeat is 183 what about gender of baby?

20 weeks for gender: Domea: the gender of the baby is usually seen at the time of your full anatomy scan which is 18-20 weeks. Sometimes it can be seen sooner or sometimes the baby's position and other factors keep us from seeing it even when you are at the right gestational age. The heart rate is not a good predictor of the baby's gender. ...Read more

A week and half ago doc measured baby at 33 weeks 6 days. Ultrasound shows 3 days ago 33 3 days. Is baby growing?

Hard to say...: Ultrasound measurements for growth in the third trimester can be off as much as 3 weeks. A week-and-a-half isn't enough time to notice a large change in the baby's growth and results can be confusing. It may not be possible to know for certain if the baby is growing in this short time-frame. You may need additional ultrasounds to know if the baby is growing appropriately or not. ...Read more

How accurate are ultrasounds at 12 weeks. is it possible to be twelve weeks pregnant and bby measure at 14 weeks?

Very: A technically good scan by a proficient sonographer or physician will be accurate to less than 1 week in the first trimester. If a 12 week scan is technically good and is interpreted correctly, it should not be possible to be off by that much; meaning the ultrasound dates are likely correct. ...Read more
