1. Is the blood test accurate eleven days after having sex?

A blood test to confirm pregnancy is to check the concentration of human chorionic gonadotropin (HCG) in the blood. HCG is derived from embryonic trophoblast cells and needs to be secreted after the fertilized egg is formed and trophoblast cells are differentiated before it can be detected in the female blood. In most patients, low concentrations of HCG can be detected 11 days after ovulation, but further testing is needed to determine whether it is a normal pregnancy. There are also women whose HCG is still very low and undetectable at this time, so it is best to continue monitoring HCG changes even if HCG is not detected.

2. How long does it take to detect pregnancy?

According to scientific research data, women can usually be diagnosed with pregnancy around 7 to 12 days into the pregnancy. The simplest and most effective way to test whether you are pregnant is to use a test strip test. The way it is tested is very simple. Women can find out whether they are pregnant by testing their urine at home. If they are pregnant, a specific hormone can be detected in the urine of the pregnant woman from the 7th to 10th day of pregnancy. The early pregnancy test strip is used to test this substance.

Early pregnancy self-test can detect whether you are pregnant 18 days after having sex or if your menstruation is delayed by 7-10 days. Because after the sperm and egg combine to form a fertilized egg, it takes 6-8 days for the endometrium to implant, and then 7-10 days for the HCG secreted by the placenta to enter the urine. Adding the two together, it is scientific to test whether you are pregnant from the urine 18 days after having sex. Pregnancy can be detected at the earliest seven days after sexual intercourse, usually around fourteen days, and occasionally more than twenty days. The diagnosis can be confirmed by self-test strips or HCG testing in the hospital.

If the test shows that you are not pregnant, but your period has not come, please go to the hospital for a blood test. But if the test shows pregnancy, it is basically accurate. Once you are sure you are pregnant, if you do not plan to keep the baby, then you should go to the hospital for a check-up as soon as possible. It is most important to develop an abortion plan to minimize the damage to your body.

If you want to know whether you are pregnant as early as possible, it is best to do multiple tests to be more accurate.
