How many days of pregnancy?

For our pregnant friends, the first thing we are most concerned about is how long we have been pregnant or how many days we have been pregnant, etc. These related questions are what we want to know most and are most concerned about. For every pregnant friend, the time of pregnancy is sometimes not fixed, because everyone's physique is different, so the time will not be exactly the same. Of course, all pregnancy times and all pregnancy days are the same.

Method: 1. The number of days and gestational age of pregnancy are calculated from the first day of the last menstrual period. .

2. The starting date of pregnancy is calculated from the first day of the last menstrual period. One gestational week is 7 days, one "gestational month" is 28 days, and the entire pregnancy period is 10 "gestational months", or 280 days, a total of 40 weeks.

3. Since it is difficult for every pregnant woman to accurately determine the time of conception, medical regulations stipulate that the expected date of delivery is calculated from the first day of the last menstrual period. The entire pregnancy period is 280 days, or 10 gestation months (each gestation month is 28 days).

Tips: 1. Calculate according to the basal body temperature curve: take the last day of the low temperature segment of the basal body temperature curve as the ovulation day, and calculate backward from the ovulation day to 264-268 days, or add 38 weeks.

2. Calculation based on B-ultrasound examination: When doctors perform B-ultrasound, they can measure the biparietal diameter, crown-rump length and femur length to estimate the gestational age and calculate the expected date of delivery (this method is mostly used by doctors for B-ultrasound examination diagnosis).

3. Calculate from the time when morning sickness starts: Morning sickness usually occurs at the 6th week of pregnancy, which is 42 days after the last menstrual period. Calculate backward from this to 280 days to get the expected date of delivery.

For those who want to know how long or how many days they have been pregnant, in addition to referring to the hospital's examination report, they can also judge based on their own menstrual days and menstrual cycle. Of course, we can also judge the number of days of our pregnancy based on many methods, so no matter which method we choose, we will get the answer we want.
