Post-transfer usually refers to the period after the patient has undergone in vitro fertilization – embryo transfer, a process also known as “IVF”. Symptoms vary from day to day after embryo transfer, depending on the treatment protocol used and the individual patient. Most patients usually have no significant symptoms for 1-5 days after embryo transfer; by 5-8 days, if the embryos are already in a state of implantation, this may lead to an increase in estrogen and progesterone in the woman’s body. Therefore, it is usually normal to experience a change in dietary preferences, bloating, breasts becoming tender, mild abdominal pain, frequent urination, and a small amount of vaginal bleeding during the 5-14 days after transfer. Embryo implantation is the result of several factors acting in concert, and any one of them may lead to failure of implantation. Medication should be administered within 14 days after transfer as prescribed by the doctor. There is no need to be overly concerned about mild symptoms to avoid anxiety, while severe symptoms require prompt medical attention. Pregnancy can be determined by testing hCG levels in blood or urine 12-14 days after embryo transfer, and premature hCG measurement is not advocated to avoid misinterpretation of the results. The doubling of blood hCG can be observed in the early stage to understand the embryonic development. Vaginal ultrasonography is needed at 4-5 weeks after embryo transfer to determine intrauterine clinical pregnancy. It is recommended to pay attention to rest after embryo transfer, avoid overexertion, and try to avoid eating cold, spicy and stimulating foods, such as cold drinks, ice cream, hot pot, etc. Maintaining a good mood and avoiding excessive emotional stress will help provide a better environment for embryo implantation. If pregnancy is detected, it is still necessary to follow the doctor’s advice and review regularly for further examination and fetus preservation measures.
