How Many Weeks Into Gestation Can A Fetus Breath
Need advice on what is the the difference between the gestational age of a fetus and how many weeks you are?
Same thing: The way you count is from your last period, it is 40 weeks from your last period until your due date so when you are 6 weeks gestational age it means 6 weeks from your last period which is how many weeks u are ( most people get pregnant 2 weeks after their last period ) but u always count from the 1st day of the last period, and in my office in coral springs, fl, i always do an early ultraosund. ...Read more

Can the reading of a 10 week gestational age be wrong? Is it possible that the crown can be larger than other fetuses?
Yes: Prenatal ultrasounds are not 100% accurate. Readings also depend on the training and experience of the tech and the ob. Ultrasonography cannot detect certain anomalies in the fetuses. There have been cases when fetuses have been aborted to find out, in the post-mortem, that they were perfectly normal. But, ultrasound remains a great diagnostic tool and many lives have been saved by it. ...Read moreSee 1 more doctor answer

My fetus is measuring 7 weeks but gestational sac is 1 week behind. Is that bad? Heartbeat is 140bpm. Is there anything i can do to help it grow?
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

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
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
