The conception of women is a very magical process. Women release one or several eggs every month, which meet with sperm in the fallopian tubes to form a fertilized egg. Afterwards, the fertilized egg implants and develops in the uterus before conception is successful. Many people want to detect pregnancy as early as possible, so can pregnancy be detected before implantation?
Can pregnancy be detected before implantation of fertilized eggs?
The answer is' no '. Because after sperm and egg combine to form a fertilized egg, the endometrium implants around 6-8 days after fertilization, and the blastocyst forms trophoblast cells. Then, 7-10 days later, the placenta begins to secrete HCG before it can enter the urine. Adding the two together, it is scientific to detect pregnancy in the urine 18 days after intercourse. The earliest time after sexual activity is seven days, but the secretion of HCG is very low. Generally, pregnancy can be detected in about fourteen days, and a few can be detected in more than twenty days. Testing HCG in the mother's blood or urine can be used as an accurate indicator for diagnosing early pregnancy, and can be confirmed by self use test strips or hospital HCG examination.
How to determine if you are pregnant
When menstruation is delayed, people often doubt themselves whether it is due to menstrual abnormalities or pregnancy, which is a common phenomenon in daily life. How to exclude pregnancy and determine if it is a menstrual disorder are the first issues that need to be clarified. First, determine if you are pregnant. If the menstrual cycle has always been normal without any signs of delay, and there are some signs of pregnancy reactions, urine should be tested with early pregnancy test strips on the fifth day after the menstrual delay. If it is positive, a gynecological pelvic examination should be conducted; If the cervix shows a purple blue change, the uterine body is full or enlarged, and there may be accompanying symptoms such as breast tenderness, nausea, etc., it can be diagnosed as pregnancy.
Of course, through routine blood and urine tests, blood pressure, weight, blood type, Rh factor, hepatitis B, syphilis tests, and ultrasound examinations, abnormal pregnancy or multiple pregnancies can be detected in advance, and pregnancy can be quickly determined.
Through the introduction in this article, it can be known that the fertilized egg has not yet formed a placenta or released HCG before implantation, while early pregnancy testing determines pregnancy by detecting HCG in urine or blood pressure. So it is impossible to detect pregnancy before the fertilized egg implants, and it can only be detected after 18 days of sexual intercourse.
