1. Can pregnancy be detected on the 9th day after intercourse?

Under normal circumstances, sperm and egg meet in the bilateral fallopian tubes (SLG) and fuse to form sperm-egg fusion. This process occurs within 12 hours after the egg is released. In other words, within 12 hours after the egg is released (or 24 hours, but the former is more common), if fertilization fails, it will be discharged through SLG and die. After the sperm and egg combine to form, they first need to break down in the SLG and grow into a blastocyst, which takes about 5-7 days.

After ovulation and intercourse for 14 days, you can use a pregnancy test strip to find out whether you are pregnant. You cannot find out on the 7th or 8th day using a pregnancy test strip. You need to go to the hospital and have a blood test to check the HCG female hormone to find out whether you are pregnant. Generally speaking, women can test whether they are pregnant about a week to 10 days after they are actually pregnant. Once the man's sperm and the woman's egg cell combine to form a sperm and egg, about 7-10 days after the embryo implants in the uterine wall, the pregnant woman's embryo will secrete a hormone called human chorionic gonadotropin.

2. How to detect pregnancy

1. Blood hCG test: Checking the hCG value through "quantitative analysis" of blood can reflect pregnancy more flexibly and accurately than the general "determination" of urine test with pregnancy test strips, and its success rate is over 99%. In addition, for multiple pregnancies, ectopic pregnancies, IVF abnormalities, language development delay, hydatidiform mole, some endocrine diseases or tumors, the blood hCG value is combined with clinical conditions and other test results, and a correct diagnosis can usually be made through comprehensive analysis.

2. Urine hCG test: Urine hCG pregnancy test is to determine whether a woman is pregnant by testing whether there is hCG in her urine. In order to improve accuracy and reduce deviation, it is best for female friends to go to the hospital outpatient department for blood hCG testing.

3. Ultrasound testing: Some women mistakenly believe that they can use ultrasound (B-ultrasound) to check if they are pregnant. In fact, it takes until about 5 weeks of pregnancy to see whether there is an embryo in the uterus. Ultrasound testing can not only check the growth of the embryo, but also detect the possibility of ectopic pregnancy.
