The test paper on day 9 of blastocyst transfer is usually not measurable, but there will be individual differences.
Blastocyst transfer refers to a method of in vitro fertilization-embryo transfer technique, which must be operated by a professional physician. Generally, it is only 2~3 days after blastocyst transfer that the embryo starts to implant, and it is only after the successful implantation that the blood hCG (human chorionic gonadotropin) starts to be secreted.
The concentration of hCG is low at the beginning, so generally pregnancy cannot be detected with pregnancy test paper on the 9th day of transfer, but there may be individual differences.
After blastocyst transfer, you should pay attention to proper rest, not to do strenuous exercise and physical labor, and follow the doctor’s instructions to continue luteal support therapy. Generally, it is necessary to carry out early pregnancy test about 2 weeks after the implantation to detect whether pregnancy, and about 4 weeks after the implantation to do ultrasonography, to be able to clarify whether it is a normal intrauterine pregnancy. After the diagnosis has been made, the patient should continue to undergo labor and delivery tests on a regular basis.
