B-ultrasound is 2 weeks younger than the last menstrual period

For expectant mothers who have irregular menstruation or forget their due date, they cannot calculate their gestational age by themselves. What should I do then? There are methods, and expectant mothers can estimate the gestational age based on B-ultrasound.

In cases like this, expectant mothers should consult a doctor as soon as possible. If they want to estimate the gestational age based on B-ultrasound, the sooner the better, and the later the error will be.

Generally, color ultrasound examinations are used to estimate the early gestational age by the head-rump diameter of the test tube embryo, and the faster the accuracy, the higher the accuracy. Generally, the statistical error of gestational age estimated by ultrasound is about 8% of the estimated gestational age, which means that the older the gestational age, the greater the error range.

In the early stage, B-ultrasound examination can be performed to accurately calculate the gestational age based on the growth and development of the test tube embryo and fetus. However, the results of B-ultrasound only indicate the current specific weeks of pregnancy, and cannot indicate that the baby is developing slowly or is underdeveloped.

I remember when I had an ultrasound at 11 weeks, the ultrasound data showed that I was 13 weeks pregnant, which was 2 weeks older than the actual gestational age. Then another expectant mother's ultrasound data showed that it was one week younger than the actual gestational age. These two results cannot mean anything, because we all remember the due date clearly, so the key is to estimate the gestational age based on the due date. The due date is also calculated based on the actual gestational age, and not just because my B-ultrasound examination shows it is 2 weeks older. Besides, any deviation in B-ultrasound within 2 weeks is within the acceptable range.

Therefore, expectant mothers do not need to worry too much. The difference between the expected date of delivery and the gestational age shown by B-ultrasound does not mean that there is a problem with the development of the baby.

For every expectant mother, the biggest wish is that the baby in her belly can grow up healthily and safely, and finally give birth successfully after ten months of pregnancy to meet her baby. However, during the prenatal examination, many mothers may encounter various unexpected events, among which it is also very common in clinical medicine that the B-ultrasound result is 2 weeks earlier than the expected date of delivery. Is it normal that the ultrasound is 2 weeks younger than the expected date of delivery? What should I do if the fetus is too small? Let’s take a closer look below!

Is it normal for the ultrasound to be 2 weeks younger than the due date?

Regarding the question of whether it is normal for the B-ultrasound to show that the baby is 2 weeks younger than the expected date of delivery, I believe that many expectant mothers are very worried. In fact, B-ultrasound is an imaging diagnostic examination, and there may be certain errors in the examination. Also, if the menstruation is irregular, the fetus may be smaller than the actual week number. Therefore, as an expectant mother, you don’t need to worry too much.

What should I do if the fetus is small?

(1) Improve nutritional content

After discovering that the fetus is small, the mother must think about whether there is anything wrong with her diet structure or method during pregnancy, whether her diet is unbalanced and lacks nutrition, or whether the mother is picky about food and does not like to eat meat. In order for the baby to catch up with the size of the pregnancy week, or to move yourself as much as possible, you need to eat more nutritious meats, vegetables and fruits every day.

(2) Proactively adjust your mindset

If you are told that your baby is too small, you must adjust your mentality in time, because there are certain deviations in the values ​​measured by B-ultrasound. If you worry and feel anxious too much, it will affect the normal growth and development of the fetus. Maintain a positive attitude and believe that there will be a way to deal with it. Doctors will also give you some good suggestions.
