Age Difference In Fetal Calculations?
Hello, I want to ask, in October I checked the ultrasound of the womb, the age of the fetus was 13week, I just had the ultrasound again, he said. But if it’s calculated manually every week it should be 36week but why is it still 32week. How is that right?
Hello Dita, thank you for the question to HealthReplies.com
Basically the most accurate determination of gestational age is through first trimester ultrasound. If the results of the calculation of gestational age from HPHT (first day of last menstruation), first trimester ultrasound, second trimester ultrasound, and third trimester ultrasound are all different, then the gestational age that should be used is based on first trimester ultrasound. However, of course there are other considerations that must be used. Ultrasound examination is very dependent on the tool and the operator (the person doing the ultrasound) as well, so you should also consider doing an ultrasound at the obstetrician and not just at the midwife.
Regarding the differences in the results of the ultrasound, you should ask directly with health professionals who do ultrasound on you. For example both ultrasound is done by midwives, you should try to confirm again by doing an ultrasound at the obstetrician. Also inform your obstetrician about the difference between the results of your initial USG and the current USG so that it can be evaluated more clearly whether there are certain abnormalities in the fetus or not (for example, if the fetus is experiencing growth disorders).
So much information from me, hopefully enough answer
