Some people can detect pregnancy very early, which may be caused by early ovulation, the use of blood HCG test, individual differences and other reasons.
1. Early ovulation: If a woman’s ovulation time is advanced, the time of the combination of sperm and egg after intercourse will be advanced, the actual time of pregnancy is early, so the time to find out the pregnancy will be relatively early.
2. Blood HCG test: If the sperm and egg combine to form a fertilized egg after intercourse, the HCG level in the blood will rise soon after the fertilized egg is deposited, so it is generally 7-10 days after intercourse, and then the blood test can be found to be positive for HCG. After another 1 week or so, HCG can be detected in the urine.
3. Individual differences: the development of the fertilized egg is not the same for everyone, some fertilized eggs develop more rapidly, the pregnancy will be detected faster, if the development is slower, the pregnancy will be detected slower.
It does not matter how early or late the pregnancy is detected; regular checkups are sufficient after the pregnancy is detected.
