Artificial cycle transfer of blastocysts belongs to one of the methods of artificial fertilization techniques, which is usually done when the patient’s uterine lining reaches a certain thickness after ovulation, in the second half of the menstrual period. Artificial cycle blastocyst transfer is generally related to the thickness of the uterine lining, a woman’s uterine lining will start to grow as soon as her menstrual period comes, and can be transplanted after the ultrasound test after ovulation, in which a woman’s uterine lining reaches a thickness of more than 0.7 to 1 cm. In addition, blood or urine tests can be taken 7 to 10 days after the transplant to determine if the transplant was successful. If the transplant is successful, there will be a significant increase in hormone levels in the blood. On the contrary, it means that the transfer has failed. If a woman experiences abdominal pain after blastocyst transfer, it is recommended to consult a doctor in time, and under the doctor’s guidance, complete the relevant examinations to clarify the cause of the disease and treat the symptoms.
