After frozen embryo transfer, the pregnancy test is related to the type of embryo transferred, and usually pregnancy can be detected on the 10th to 14th day. The early detection of pregnancy after frozen embryo transfer is related to the maturity of the transferred embryos. If the embryos are day 3 blastocysts, pregnancy can usually be detected 14 days after the frozen embryo transfer; if the embryos are day 5 blastocysts, pregnancy can usually be detected on the 12th day after the frozen embryo transfer; and if the embryos are day 6 blastocysts, pregnancy can be detected on the 11th day after the transfer. It is generally recommended that patients go for a pregnancy test after 14 days of transfer. In addition, if there are any abnormal symptoms during the transfer process, consult a doctor to complete the relevant examinations in time to avoid delaying the treatment.
