How long does IVF know if it is pregnant?
Test tube baby transplantation is a common assisted reproductive technology in recent years, which enables couples who cannot conceive naturally to realize their dreams of childbirth. However, many couples want to know whether pregnancy is successful as soon as possible after undergoing IVF transplantation. How long will we know if we are pregnant after IVF transplantation? It will be described in detail from the following aspects.
Common reactions after embryo implantation
After IVF transplantation, some common reactions may make women feel pregnant. The most common symptoms are breast pain and abdominal pain. This is due to the change of endometrium after embryo implantation. In addition, some women may also have symptoms such as itchy nipples, dizziness and frequent urination. Not every woman has these reactions, so we cannot judge whether pregnancy is successful from these symptoms alone.
In addition, the key after IVF is embryo implantation. About two weeks after embryo implantation, embryo implantation of IVF began to occur, but at this time, it was impossible to determine whether pregnancy was possible by any means.
Beta hCG detection time
Beta hCG is a special biochemical indicator that can provide information on the success of IVF transplantation in early pregnancy. In general, Beta hCG testing should be performed 10 days after embryo implantation. After normal pregnancy, the embryo implanted into the uterine wall will produce hCG hormone in the body, and the content of this hormone will reach a detectable level about 10 days after pregnancy. Therefore, Beta hCG test can effectively judge whether pregnancy is successful.
However, it should be noted that sometimes Beta hCG test may produce negative results, but it will become positive in subsequent tests. This may be due to the changes in hormone levels after embryo implantation, so it is recommended to conduct another test a few days after the negative results to ensure the accuracy of the results.
Ultrasonic inspection
Ultrasonic examination is a reliable method to determine the success of IVF transplantation. About 4-5 weeks after IVF implantation, the embryo begins to have heartbeat and form embryo sac. At this time, the doctor can observe the development of the embryo through ultrasonic examination and determine whether the pregnancy is successful.
It should be noted that in the first few weeks after embryo implantation, the embryo may not be observed by ultrasonic examination, which does not mean that the transfer failed. During this period, you need to wait patiently and follow the doctor's instructions for reexamination.
summary
How long we can know whether or not we are pregnant after IVF transfer depends mainly on the time after embryo implantation and the test method used. The common reaction after embryo implantation cannot determine whether the pregnancy is successful, but Beta hCG detection and ultrasound examination are the key to determine whether the pregnancy is successful. Using the normal cycle as a reference, Beta hCG detection was performed 10 days after embryo implantation, and ultrasonic examination was performed about 4-5 weeks, which can accurately determine whether the IVF transfer was successful.
In conclusion, it is very important for couples who are trying IVF transplantation to be calm and patient. If you have any questions or concerns, it is recommended to consult a doctor in time for professional guidance and help.
