The second blood test showed pregnancy

Generally, pregnancy can be detected ten days after intercourse. If the embryo implants late, the hCG value in the woman's body is not high and may not be detected. However, pregnancy can be detected within 14 days after intercourse. In addition, it may also be due to biochemical miscarriage or ectopic pregnancy, which causes the body's hCG value to rise slowly, thus affecting the test results. So is it accurate to have the second blood test show pregnancy information?

The second blood test showed pregnancy information, which means that the first blood test was less than 8 days after intercourse, and the level of human chorionic gonadotropin in the body had not yet increased, so it could not be detected. After a woman is successfully inseminated, the fertilized egg moves into the uterus and the embryo implants. During the process of forming the test tube embryo, the embryo transforms into trophoblast cells and begins to secrete a large amount of HCG, which is secreted into the urine through the pregnant woman's blood circulation system. Generally, the HCG level will increase rapidly during 1-2.5 weeks of pregnancy, and reach its peak at 8 weeks of pregnancy. If the blood test is within 8 days of sexual intercourse, it may not always show any result because the level of human chorionic gonadotropin is still relatively low. In most cases, if pregnancy is successful, generally more than 8-10 days after intercourse, a positive index can be detected through blood HCG test.

After pregnancy, the levels of human chorionic gonadotropin (HCG) and progesterone (PG) will increase rapidly with the increase in the number of weeks of pregnancy. It reaches its peak at 12 weeks of pregnancy and remains at this level until the pregnancy is complete. Usually we go to the hospital for a "blood test" to test the content of these two hormones in the body to determine whether we are successfully pregnant. If “the second blood test showed pregnancy”, it may be that the female hormone level was low during the first test and the pregnancy could not be confirmed. As time went by, the female hormone level gradually increased, and the pregnancy was confirmed by the second test.

If the blood test shows pregnancy for the second time, the success rate is 100%. For most women, under normal menstrual regularity, if the menstrual cycle is 28-30 days, or about 31-32 days after menstruation, a blood test for HCG can show pregnancy. However, because the moon is affected by the environment and the state of mind, once there is an anxious state of mind or a change in emotions or a change in the environment, it may cause changes in the menstrual cycle, so the time of ovulation will also change to a certain extent. Therefore, it is possible that pregnancy cannot be detected through blood tests 31-32 days after menstruation, and pregnancy can be detected through blood tests a few days later. In clinical medicine, the success rate is very high and it is normal. If you want to get pregnant again after being pregnant, you need to improve your nutrition and do regular pregnancy checkups. If you don't want to get pregnant again, it is best to go to the gynecology department for further examination and then choose to terminate the pregnancy.
