The first day of successful conception has no obvious signs in most patients.
For most women with normal menstrual periods, the possibility of pregnancy is highly suspected if symptoms of menopause persist for more than a week during sexual intercourse without any contraception.
In most cases, there are no obvious symptoms on the first day of conception, and most women do not feel them. Only after waiting for a period of time, through their own symptoms and clinical examination can be clear whether there is pregnancy or not.
Women who want to know if they are pregnant can go to the hospital for blood and urine tests to check for human chorionic gonadotropin, or ultrasound to find out if there is a gestational sac in the uterine cavity, and then make a diagnosis of pregnancy.
