Early intrauterine pregnancy means that you are already pregnant and in the early stages of early pregnancy. For women of childbearing age with regular menstruation, early pregnancy is highly likely once the menstrual period has passed for 10 days or more, or when the basal body temperature is monitored and the high temperature value continues for 18 days without dropping. When the pregnancy test is positive (two red lines on the pregnancy test strip), and the pregnancy ring cannot be seen on ultrasound, or the pregnancy ring can be seen, but the embryo buds and heart tube pulsation cannot be seen, then it is called intrauterine early pregnancy. When early intrauterine pregnancy is identified, pregnant women should pay attention to rest and diet, observe whether there is morning sickness and other early pregnancy reactions, it is best to go to the hospital after 7 weeks of pregnancy for ultrasound examination to confirm the diagnosis of early pregnancy and live birth.
