A few days after sex can be detected pregnant

After sex life, if you want to check if you are pregnant, you need to be pregnant for more than a week at the earliest, because there are two ways to detect pregnancy, one is to check through the changes of human chorionic gonadotropin in the blood, and the other is to check through the human chorionic gonadotropin in the urine, because the human chorionic gonadotropin in the blood changes faster, and after the sperm and egg combine, it will begin to show a certain degree of change. Therefore, more than a week after the same room can be tested through blood, if not anxious, can be tested through urine more than two weeks after the same room.
