With cleavage embryo transfer, pregnancy can be detected after about 8~10 days. Fissured embryo transfer is the transfer of embryos that have been cultured in vitro for 2~3 days, and it takes at least about 8~10 days to detect pregnancy by checking blood HCG. Due to the different body types of individuals, the time of implantation is also different, some implantation is later, and the test results are delayed. Try to wait for 2 weeks after the transfer of cleavage embryo to do blood HCG test, to avoid the early test results due to false-negative, increase the patient’s anxiety, and even affect the development of the embryo. After the transfer, pay attention to keep the mood happy, try to lie flat and rest, to increase the chance of successful transfer. The specific time of testing after the transfer of cleavage embryos, try to consult the surgeon, according to the situation of the transfer, the characteristics of the patient and then choose the time.
