Normally transferring a 5 day blastocyst on the sixth day is not measurable. The transfer of blastocysts is usually embryos that have been cultured for 5 to 6 days, and the transfer of 5-day blastocysts on the sixth day may not be detectable because the time is too short. Generally at least one week after blastocyst transfer can measure whether women are pregnant or not, so it is recommended that at least one week after blastocyst transfer, you can go to the regular hospital to draw blood to check the blood of human chorionic gonadotropin to detect whether the pregnancy is successful or not. After blastocyst transfer, you need to pay attention to rest, keep a good state of mind, avoid nervousness and anxiety, ensure enough sleep time, avoid staying up late, heavy labor and prolonged sitting and standing, and pay attention to personal hygiene and so on. If the conception is successful, you should also pay attention to more rest during pregnancy, eat a light diet, and take regular obstetric examinations.
