There are no obvious signs of pregnancy for 10 days, but depending on the age, physical fitness and work pressure of individuals, some women may experience physiological discomfort such as swelling and soreness of the lower back and abdomen, and easily feel tired, especially in advanced maternal age and multiple pregnancies. The swelling and soreness of the lower abdomen at the beginning of pregnancy is a physical abdominal discomfort caused by pregnancy, which is a normal physiological phenomenon, and may be triggered by the early embryonic implantation, the pulling of the uterine ligaments, and the accelerated metabolism in the body due to changes in hormone levels. It is aggravated by exertion and can be relieved after lying down and resting. At this time, you should avoid bending and squatting, pay attention to maintenance, prevent from getting cold, eat less spicy and sour food, and apply hot compresses locally, which can be effectively regulated. Some women may experience some early pregnancy-related symptoms, such as menopause and early pregnancy reaction. Menorrhagia is the earliest symptom of early pregnancy. For women of childbearing age who have normal sexual life, pregnancy should be highly suspected once the menstrual period reaches 10 days or more (10 days of menopause) if they have regular menstruation. Early pregnancy reaction can occur after pregnancy due to the change of hormone level in women’s body, such as cold, dizziness, weakness of limbs, drowsiness, nausea and vomiting, dislike of greasy and sour food, etc., which mostly appear around 6 weeks after menopause and disappear on their own around 12 weeks; the reaction can be light or heavy due to different physical qualities of individuals, and can be relieved after paying attention to diet and rest in light cases; in heavy cases, hospitalization is needed for rehydration and adjustment, such as severe pregnancy vomiting, due to The nausea and vomiting reactions are so severe that it leads to inability to eat and water, disruption of electrolytes (mainly K ions) in the body, increase of ketone bodies, miscarriage or maternal ketoacidosis in severe cases. Clinically, since the signs and symptoms of new pregnancy are not obvious, doctors mainly rely on auxiliary tests to clarify pregnancy and the time of pregnancy, such as qualitative and quantitative determination of blood HCG, vaginal ultrasound, etc.
