When there is no pregnancy test, you can determine whether you are pregnant by taking a blood HCG test and ultrasound. Pregnancy is the process by which a sperm combines with an egg to form a fertilized egg, and menopause is a characteristic sign reflecting pregnancy. In the early stages of pregnancy, blood levels of human chorionic gonadotropin are elevated, allowing for an earlier detection of pregnancy. After menopause for a longer period of time, you can determine whether you are pregnant by ultrasound. If you are pregnant, you can see the gestational sac inside the uterus, and you can even detect the fetal buds and the fetal heart. Urine pregnancy test is the easiest way to determine pregnancy, but there are some errors. Ultrasound is the gold standard for early diagnosis of pregnancy, not only can it determine whether you are pregnant or not, but also can determine whether you are pregnant inside the uterus or outside the uterus, please consult your physician for specific advice.
