How to estimate the expected date of delivery after successful pregnancy of test tube baby
IVF refers to the babies who are conceived in the laboratory using assisted reproductive technologies such as artificial insemination or in vitro fertilization. Once pregnant successfully, expectant mothers usually can't wait to know their due date of birth so as to prepare for the coming baby. The estimation of the expected date of birth is very important, so that doctors and expectant mothers can better arrange prenatal examination and post natal care. Next, we will elaborate on how to estimate the expected date of IVF from four aspects: ultrasonic examination, embryo development, periodic monitoring and egg retrieval date.

Ultrasonic inspection
Ultrasonic examination is one of the most commonly used methods to determine the expected delivery date of test tube babies. Usually, the first routine ultrasound examination is performed 6-7 weeks after conception, and the doctor will determine the precise date of conception by checking the size of the fetal sac, fetal heart rate and other indicators. Thereafter, an ultrasonic examination was carried out every 4-6 weeks to observe the development of the fetus and further adjust the expected delivery date. Through ultrasonic examination, doctors can accurately estimate the expected date of delivery of test tube babies.
In addition, ultrasound can also help eliminate pregnancy complications and risks of abnormal fetal development, such as early abortion, ectopic pregnancy, etc. Therefore, expectant mothers must carry out regular ultrasonic examinations according to the doctor's recommendations to ensure the safety and smoothness of pregnancy.
embryonic development
Embryonic development is also an important basis for estimating the expected date of delivery of IVF. Generally, the time from egg retrieval to embryo implantation is 3-5 days, and about two weeks after implantation, there will be signs of underlying formation and pregnancy. According to the days of embryo implantation and the indicators of embryo development, doctors can preliminarily estimate the expected date of conception.
However, there may be differences in embryo development under different circumstances, for example, the rate of embryo development is too fast or too slow, which may affect the calculation of the expected delivery date. Therefore, expectant mothers need to keep close contact with doctors and make timely inspection and adjustment.
Periodic monitoring
Periodic monitoring is one of the methods to help estimate the expected delivery date of IVF by measuring follicle growth and endometrial thickness. Before IVF, doctors usually monitor the mother's menstrual cycle in detail, and determine the best time for follicle growth and endometrium through experience and scientific methods. In this way, doctors can preliminarily estimate the expected delivery date of IVF.
However, periodic monitoring is only a preliminary estimation method, and the specific calculation of the expected production period needs to be comprehensively evaluated in combination with other factors. Mothers to be should work closely with doctors to monitor and adjust periodically according to their guidance.
Egg retrieval date
The date of egg retrieval can also be used as a reference for estimating the expected date of IVF. Usually, 14 days after the egg retrieval is fixed, and expectant mothers can calculate the expected date of IVF babies according to the date of egg retrieval. However, the date of egg retrieval is only a part of the estimation of the expected spawning date, which needs to be comprehensively evaluated in combination with other factors.
To sum up, ultrasonic examination, embryo development, cycle monitoring and egg retrieval date are the most commonly used methods for estimating the expected delivery date of IVF. Mothers to be should work closely with doctors to check and adjust according to their suggestions to ensure the safe and smooth birth of IVF.
