Generally pregnancy is not always detected at seven days of IVF transfer, but there can be individual variations. IVF refers to in vitro fertilization-embryo transfer technique, which needs to be operated by a professional physician. Generally 3~4 days after the embryo transfer is the implantation, but the implantation time will also exist differences, the latest not more than 7 days, so some women in the transfer of 7 days can be detected pregnancy, but generally more will be in the transfer of 10-14 days after the blood or urine hCG test to confirm pregnancy. After embryo transfer, we should pay attention to proper rest, avoid strenuous exercise and exertion, prohibit coitus, eat a light diet, and follow the doctor’s instructions to continue to give progesterone supportive therapy, usually 4-5 weeks after the transfer of ultrasound to confirm whether the pregnancy is intrauterine. Therefore, on the seventh day after IVF embryo transfer, some patients are able to check whether they are pregnant or not, but some need to be measured later.
