It is not uncommon for there to be a discrepancy between the gestational age calculated based on your last menstrual period (LMP) and what is measured during an ultrasound. The LMP calculation assumes that ovulation and conception occurred on day 14 of your menstrual cycle, which may not always be accurate.
Ultrasound measurements are considered more accurate in determining gestational age as they take into account various factors such as fetal size, development, and growth rate. However, even ultrasounds can have a margin of error.
In your case, the ultrasound shows that you are slightly behind in terms of gestational age compared to what was calculated based on your LMP. This could be due to variations in individual growth rates or differences in ovulation timing. As long as there are no other concerning factors or complications identified by your healthcare provider, this discrepancy is generally considered within normal range.
The fetal weight of 1197 grams falls within an acceptable range for this stage of pregnancy. Fetal weight can vary depending on multiple factors such as genetics, maternal health, and nutrition.
It is important to discuss any concerns or questions you have with your healthcare provider who can provide personalized guidance based on your specific situation. They will monitor your pregnancy closely through regular check-ups and additional ultrasounds if necessary to ensure both you and your baby are healthy.
