How long does it take for IVF to detect pregnancy?

If the test tube embryos transferred during in vitro fertilization are on the 3rd day, then the pregnancy test should be done two weeks after the transfer. If the embryos transferred are on the 5th day, then the pregnancy test should be done 12 days after the transfer. If the embryos transferred are on the 6th day, then the pregnancy test should be done 11 days after the transfer. However, some patients can test positive for pregnancy 1-2 days earlier than the required time. This varies from person to person. Blood HCG is more accurate than urine HCG. Therefore, you must go to the hospital to have your blood drawn for HCG testing. Regardless of whether your urine test for HCG at home is positive, you must go to the hospital outpatient department to do a blood HCG test.

In vitro fertilization is a pregnancy-promoting technology that uses female eggs and male sperm to meet in a special test tube to produce sperm and egg fusion, and then transplant the sperm and egg fusion into the woman's uterus to allow the embryo to implant and develop. After the sperm and egg are combined and transplanted, they will also go through the process of embryo implantation before they can grow and develop, which is not much different from the process of embryo implantation and development after normal fertilization. The process of embryo implantation generally takes about 7 days. In other words, after the sperm and egg are combined and transplanted, the blood HCG value can be measured in about 7 days at the earliest.

However, in the early stage of embryo implantation, it may be affected by some harmful factors, which may cause the embryo to fail to implant and the test tube embryo to stop growing and developing. It is best to measure the blood HCG value around the 14th day after the test tube transplant to check whether the pregnancy is successful. Two weeks after confirming the pregnancy, a color Doppler ultrasound examination can be performed to observe the growth and development of the fetal sac.

There are three ways to check whether you are pregnant: First, you can test it out 5 to 7 days after your period is delayed, and you can use an early pregnancy test strip. Second, you can also do a blood hcg test based on the time of sexual intercourse between the couple, which is also more accurate. Generally, it can be detected 10 days after sexual intercourse. Third, you can also do an ultrasound examination 10 days after your period is delayed, which can immediately show the size of the gestational sac and its specific location. After confirming pregnancy, you should pay attention to adequate rest, avoid strenuous activities, and strictly prohibit sexual intercourse, because miscarriage is very likely to occur in the early stages of pregnancy.
