Most pregnancies can be detected by taking your pulse when you are about 40 days pregnant. It requires a professional TCM doctor to take the pulse to be more accurate, but it is difficult to tell if the pregnancy sac is inside or outside the uterus by taking the pulse. If pregnancy is detected by taking the pulse in early pregnancy, further tests, such as ultrasound or color ultrasound, are needed to not only check the development of the gestational sac, but also to rule out ectopic pregnancy. If the gestational sac and fetus are well developed, the pregnancy can continue. In early pregnancy, you should pay attention to rest, avoid strenuous activities, enhance nutrition, eat more vegetables and fruits, do not abuse drugs, and take folic acid tablets every day in the first trimester to prevent fetal neural tube development defects.
