How Many Weeks Into Gestation Can A Fetus Breath
Would there be a (big) difference in the measurement if a 12wk old fetus compared to a 9wk old fetus? The gestational age would be determined in u/s?
Yes: An first trimester sonogram is fairly accurate at dating a pregnancy (within a margin of error of about a week). At 12 weeks menstrual age with a viable pregnancy a sonogram measurement of 9 weeks would change the dating of the pregnancy and your due date should be based on that sonogram. Later sonograms should not change this established date. ...Read more
When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more

Profound.: High blood sugar during fetal development can lead to excessive growth (macrosomia), predispose to adult diabetes mellitus, increase the risk for cesarean section, shoulder dystocia and fetal death from cardiac arrhythmias and hypertrophic cardiomyopathy. Most women with gdm have normal outcomes, but are at increased risk for all of the above, as well as polyhydramnios, preeclampsia (hypertension). ...Read more

After the 6th or 7th week of pregnancy does the fetus double in size, causing the gestational age to be off?
Early pregnancy: The rate of growth of the fetus in the first trimester is very rapid. An ultrasound in the first trimester has only a 3-6 day error while later in pregnancy that error grows to 3 weeks. The gestational age is more accurate in early pregnancy and less likely to be off in the first trimester. ...Read more
Sonographer could not see fetus (only gestational sac) and said I am 5wks 2days. Do you think everything is ok with baby? Or is it just too early?
Very Good Question: With early ultrasound, it is now possible to see embryo heart motion as early as 6 weeks. While your concern is valid, repeating the ultrasound in 1-2 weeks will reveal the health of the pregnancy. Early pregnancy failure is a possibility I am sorry to say. However, if you do make it to 8 weeks with an embryonic heart beat, the chances of loosing the pregnancy drop dramatically to about 3%. ...Read moreSee 2 more doctor answers
Why are fetuses measured by gestational age and not by the actual fetal age? So if u are 12wks the measurements are actually of a 10 week old fetus?
Math: Gestational age is based on your last period..The best way we can estimate fetal age....After doing thousands of measurements standards have emerged...So if you are 12 weeks and the baby is 10 weeks in size, it would indicate a smaller baby at this time...Just a way to follow growth of the baby. If I am off, i hope an OB wills set the record straight. ...Read more
Fetus measurements: 57mm 12 weeks gestation / 62mm 12 wks+4days gestation. Are measurements this precise to have this difference in size in 4 days?
Sort of: Yes, the measurements on average do correspond to these dates and they are fairly accurate, but not exact. Also it is dependent on how the ultrasound tech measures it. So there are plenty of sources of mild error. ...Read more
