How many days are there in 12 weeks of pregnancy

If the menstrual period is very normal, that is, once every 28 days, the period from pregnancy to delivery is 280 days, that is, when you calculate from the first day of the menstrual period to 280 days, it is the delivery date. It is normal for pregnant women to give birth within the first half month and the second half month of the due date. If your menstruation is irregular, you should calculate the baby's size according to the first B-ultrasound during pregnancy to determine the due date. The error of the baby's size by B-ultrasound in the early stages of pregnancy will not exceed one week, so irregular menstruation should be based on B-ultrasound examination as a basis for calculating the expected delivery date.

The duration of pregnancy is counted from the first day of the expected date of delivery. The seventh week of pregnancy is 49 days of pregnancy, calculated as a 7-day week. The seventh week of pregnancy is in the early stages of pregnancy and is a critical period for the formation of the embryo. During this period, you should increase nutrition, maintain a happy mood, get enough sleep, avoid exposure to radiation and harmful substances, and do not abuse medication. Take folic acid orally until the third month of pregnancy to prevent neural tube defects in the fetus. It is recommended to go to the hospital for color Doppler ultrasound at an appropriate time to check whether the gestational sac, test tube embryo, etc. are growing and developing normally.

One week of pregnancy generally refers to 37 days after menstruation. During this time, the gestational sac cannot be seen through B-ultrasound. It is clinically recommended that if there is no discomfort, an ultrasound examination can be done 45 days after menstruation. About 6 weeks of pregnancy, clinically, fetal bud tissue can be seen through B-ultrasound examination. Around 7 weeks of pregnancy, initial primitive heart beats can be seen through B-ultrasound examination. Therefore, regular maintenance is recommended during pregnancy.

If you experience irregular vaginal bleeding or lower abdominal pain after menopause, go to the hospital for a check-up at any time. You can have a blood test to check the HCG and progesterone levels, and test again every other day to basically determine whether it is an intrauterine or ectopic pregnancy. In addition, the location of the gestational sac must be determined through B-ultrasound examination.
