Pregnancy does not come with menstruation next month. The main clinical symptom of pregnancy is menopause, and menstruation will not occur during pregnancy or for a short period of time after delivery. Healthy women of childbearing age, with a history of sexual intercourse, who normally have regular menstrual cycles, should be considered pregnant once they menstruate, and pregnancy should be highly suspected if it is more than 10 days past due. Shortly after the fertilized egg is deposited, elevated levels of HCG (human chorionic gonadotropin) can be detected in the subject’s blood by radioimmunoassay. Clinically, early pregnancy test paper is often used to test the urine of the test subject, which can be used to determine whether pregnancy is initially. It is also necessary to combine with ultrasound to determine whether it is an early intrauterine pregnancy. If you decide to continue with your pregnancy, you should follow your doctor’s instructions and have regular checkups. If you do not plan to have a baby, you should choose a suitable way to terminate the pregnancy under the guidance of your doctor.
