You already have the results, you are pregnant, congratulations! And immediately you start to do the math, you want to know the date of delivery. Nine months and your baby will be born. But is it nine months, 40 weeks or 280 days? We give you some information and rules that can guide you to know the day your child will be born, but be careful! statistically only 4% of babies are born on the exact date that had been said. 70% are born in the ten days close to this. And 90% between week 38 and 42 of gestation.
It may also be that due to circumstances you have a scheduled delivery, in that there is no mistake, or yes, who knows! If you can advance or sneak in an extra day. Here's a article with details of scheduled deliveries.
Nagele's Rule
This rule for calculating the date of delivery is well known and the most common. The rule consists of subtract three months and add seven days to the first day of your last period. This result is the most probable date for the baby to be born if everything has developed normally. For example, if you had your last period on April 1, you subtract three months, that is, January 1 (noting that January has 31 days and February 28, but to calculate) you add 7 days to this date. And with this rule your baby would be born for Kings, more or less. As I have told you, this is not an exact rule, but it is more or less reliable.
To calculate the date it is assumed that the woman has a regular period of 28 days, that we are all fertile during the same days and things like that. But the reality is that if the duration of a pregnancy is 280 days, 40 weeks are calculated from the first day of the last menstruation or 38 weeks if you know the specific date of fertilization. But there are issues that can influence childbirth.
What is a gestograma or pregnancy wheel?
A gestograma is a calendar, in the form of a wheel that gynecologists have to know the date of delivery. According to the measures and the weight of the fetus are known, week by week, the age of the unborn. Now you can find these gestograms online, and thus follow the evolution of your baby.
These values of Fetal weights and measurements are averages. They are pure statistics and are intended for developed countries and white people. In China or the Congo, to give you an example, other averages would have to be taken. If I tell you this, it is because your ultrasound data does not have to coincide with the gestogram data, it is the gynecologist who must interpret them for you.
So trust more delivery date that the specialist tells you, and that it will calculate when taking the measurements of the fetus, which can be in the first weeks of pregnancy or in the ultrasound of week number 12. Remember that sChildbirth that occurs between weeks 38 and 42 of pregnancy is considered normal, that is, 28 days of margin. So knowing an exact date is pure speculation.
