How should pregnant IVF babies determine their due date?
Pregnant IVF is achieved through assisted reproductive technology. For these families, it is very important to determine the expected date of birth. The expected date of birth is an important basis for pregnant women and doctors to make prenatal plans, and it is also a critical moment for families to prepare for the newborn. This article will introduce the methods to determine the expected delivery date of IVF from different aspects.
1. Menstrual history and abdominal ultrasonography
For most IVF expectant mothers, the cycle of pregnancy through assisted reproductive technology may be irregular. However, understanding your menstrual history can be an important reference for predicting the expected date of delivery. On average, pregnant women usually have menstruation within 14 days after ovulation. If the menstruation is more regular, you can use the method of calculation to predict the expected date of delivery.
In addition, abdominal ultrasound is one of the routine ways to determine the expected date of delivery of test tube babies. Doctors will evaluate the development of the fetus by observing the fetus, and then determine the expected date of delivery. At the same time, ultrasound can also check the placenta and uterus to ensure a good pregnancy, which is particularly important for high-risk pregnant women.
Once the expected date of delivery is established, doctors will make personalized prenatal plans according to the specific conditions of pregnant women and the development of pregnancy to ensure the safety of mothers and babies.
2. Ultrasonic examination of the last menstruation and early pregnancy
The expected date of IVF can be estimated by the date of the last menstruation. Under normal circumstances, a monthly cycle is 28 days, ovulation generally occurs on the 14th day of the cycle, and fertilization will occur within 12-24 hours after ovulation. Therefore, by the date of the last menstruation, plus 14 days and minus 3 months, we can roughly estimate the expected date of delivery.
However, for some IVF mothers to be, the menstrual cycle may be irregular, or the menstrual data may not be reliable. In this case, early pregnancy ultrasound can provide a more accurate delivery date. Through ultrasonic technology, doctors can observe the development of embryos, and then determine the pregnant woman's due date.
Ultrasound examination in early pregnancy is usually carried out during 6-8 weeks of pregnancy. At this time, the fetus has formed a heart and placenta. Doctors can evaluate the progress of pregnancy and the expected date of delivery by observing the size of the fetus and the fetal heart rate.
3. Gestational week and fetal growth curve
Gestational weeks and fetal growth curves are another way to determine the expected date of delivery of test tube babies. By measuring the height of the uterus of the pregnant woman and the growth of the fetus, the gestational week and the expected date of birth can be calculated. This method is especially suitable for pregnant women whose abdomen can be easily touched, for example, fat abdomen is easy to touch, while slender pregnant women are not suitable.
The doctor will compare the height of the pregnant woman's uterus with the gestational week. The relationship between the height of the uterus and the gestational age is based on the size of the pregnant woman's abdomen and the growth of the fetus. By understanding the fetal growth curve, doctors can estimate the expected date of delivery.
4. IVF birth center
The determination of the expected date of IVF can also rely on the help of IVF birth centers. The birth center will provide professional medical services, including ultrasound examination, physical examination of pregnant women and pregnancy tracking, to help expectant mothers determine the expected date of delivery.
IVF centers usually have advanced medical equipment and experienced doctors, and have unique advantages in pregnancy monitoring and prediction. In cooperation with the birth center, expectant mothers can receive comprehensive care during pregnancy in time to ensure the health of mothers and babies.
summary
It is very important for families to determine the expected delivery date of pregnant IVF babies. By understanding the history of menstruation, conducting ultrasound examination, observing the fetal growth curve and seeking the help of the fertility center, the expected date of IVF can be determined relatively accurately. Timely determination of the expected date of birth can help expectant mothers and families to prepare for childbirth, while ensuring the safety and health of mothers and babies.
