Many people think that a woman is pregnant for more than 42 days to find out, but this is not true, a woman can be checked after 10 days of pregnancy. It takes about 4 days for the egg to reach the uterus and another 2-3 days for the fertilized egg to settle in the uterine lining. After the fertilized egg has settled in the uterus, the chorionic villi will produce a hormone called human chorionic gonadotropin, which will be excreted along with the woman’s urine, at which time the woman can use an early pregnancy test to check if she is pregnant. The body will be affected by the hormone during ovulation and the body temperature will rise by 0.3-0.5°C. If the woman does not become pregnant during ovulation, the body temperature will drop to the original body temperature in about 7 days.
