38 weeks of pregnancy is 9 months and 2 weeks. The month of pregnancy is not calculated by taking 30 or 31 days as 1 gestational month, but by taking 28 days as 1 gestational month and 1 gestational month as 4 weeks, so 38 weeks of pregnancy is 9 months and 2 weeks. For women with regular menstrual cycles, the due date is usually calculated from the first day of the last menstrual period, and the month minus 3 or plus 9 and the number of days plus 7 is used to calculate the due date. However, for women with irregular menstrual cycles, instead of the above method, the due date is usually estimated by measuring the femoral diameter and head and hip diameter by ultrasound. After pregnancy, it is important to establish a pregnancy book at the obstetrics department of the hospital in a timely manner and to conduct pregnancy tests on time and monthly. The 38th week of pregnancy is close to delivery, and at this time, pregnant women should pay attention to moderate exercise and nutrition for better delivery. Pregnant women are advised to pay attention to pregnancy check-ups and to consult the obstetrics department immediately if there are symptoms such as redness, water breaking and regular contractions.
