When you have intercourse and ejaculate inside your body, you want to find out whether you are pregnant or not. First of all, you can buy an early pregnancy reagent about twelve days after intercourse, and use morning urine to test to rule out the possibility of pregnancy. Because the sperm and egg need to reach the mother’s blood circulation after the combination, and then reach the urine is a process. After the test, if there are two bars, even if the second bar is not particularly visible and is relatively shallow, there will still be a pregnancy, because the number of days of pregnancy will be relatively short, so there will be such a situation. If you want to determine whether there is an intrauterine pregnancy, you must start counting from the first day of your last menstrual period, and you can go to the hospital for an ultrasound in about forty days to determine whether there is a gestational sac in the uterine cavity and whether there is an intrauterine pregnancy, because not all pregnancies are intrauterine.
