For women with regular menstrual cycles, a positive result can be obtained by taking an early pregnancy test about 2 weeks after intercourse. For women with delayed menstruation, a positive result can be delayed for about 1 week. After a woman has intercourse during ovulation, it takes about a week for the fertilized egg to reach the uterine cavity and take up residence, at which time the HCG level in the patient’s body gradually increases. However, due to the low sensitivity of the early pregnancy test, it usually takes more than 2 weeks of pregnancy to obtain a positive test result. In women with irregular periods, a positive result may appear later. If the result of the blood HCG test is done in the hospital, combined with the vaginal ultrasound, a clear diagnosis can be made earlier. Women who do not need to have children should terminate their pregnancy by abortion or other means at 7 weeks of menopause. Those who are fertile should go to the hospital for regular prenatal checkups as prescribed by the doctor. Women are prone to miscarriage in the first 3 months of pregnancy, so they should take rest, strengthen nutrition, avoid cold, pay attention to the rhythm of life, and avoid overwork.
