Calculate gestational age based on the size of the gestational sac

Some women do not fully understand the pregnancy process because it is their first pregnancy. But everyone knows that the gestational sac is the most important component. Sometimes it is easy to forget your pregnancy cycle, that is, the gestational age. Or maybe when you were pregnant, you didn't have a clear idea of ​​the gestational age. However, the gestational age must be kept track of in each period. So how do you calculate the gestational age based on the size of the gestational sac?

How to calculate gestational age based on gestational sac

The size of the gestational sac is equivalent to the development of the embryo. As the pregnancy progresses, the gestational sac gradually becomes larger.

It is impossible to accurately determine the number of weeks of pregnancy based on the size of the gestational sac, because each pregnant woman has individual differences in her physical constitution. Even for two mothers who are pregnant at the same time, the developmental indicators of the fetus at different stages are different. This is related to the height, physique of the pregnant woman and the genetics of both husband and wife. But according to reference data, a gestational sac of 34*54*29 in size indicates about two months of pregnancy. Usually, in order to facilitate the calculation of the gestational age of pregnant women, obstetricians and gynecologists will count four weeks as one month, which means that you may be seven or eight weeks pregnant, but this is just an estimate.

Method for calculating the weeks of pregnancy: In medicine, the first day of the last menstrual period before pregnancy is usually used as the first day to start counting the weeks of pregnancy.

Taboos about due date

1. Avoid being anxious and impatient. Some women are impatient and anxiously look forward to early delivery before the due date. They become even more anxious after the due date and even abuse Chinese and Western medicines to induce labor. This mood can also have an adverse effect on childbirth. It is normal for the due date to be advanced or delayed by ten days due to certain activity periods. However, if the baby has not been born more than 10 days after the due date, you should ask a doctor to find out the reason.

2. Avoid excessive tension. Excessive mental tension will increase the body's sensitivity to external stimuli, and even slight external stimulation will cause pain. Therefore, pregnant women should eliminate their worries and maintain a happy and relaxed mental state before giving birth.

3. Avoid neglecting health care during pregnancy. The delivery of the fetus mainly depends on the contraction of the uterus and abdominal pressure. "Forcing" the fetus out of the uterus consumes a lot of energy. If you don’t eat well or sleep well before delivery, it will be very detrimental to the delivery. Before giving birth, you must pay attention to nutrition, eat small meals frequently, make sure to drink enough water, eat well and sleep well, so that your body has sufficient energy and is full of energy to complete the arduous task of giving birth.

The above is the relevant content and detailed introduction about "How to calculate the gestational age based on the gestational sac". The pregnancy cycle can only be approximated, and a difference of one to two weeks is normal. There is no need to worry too much, because the pregnancy period needs some basis to calculate, and the subjective factors are relatively large, which leads to errors. It is best to refer to the actual production time.
