Share Pregnancy calculator: know your probable date of birth

Armando @armando_bastida

One of the most typical doubts during pregnancy is when the baby will be born. In fact, in the ranking of questions asked to a pregnant woman, I would say that it would be necessary to place in first position the one of "How much are you?", Which is accompanied by "When do you get out of accounts?".

With the response of the woman, people get an idea of ​​how many weeks she has been pregnant and how many weeks before giving birth, knowing well the moment of pregnancy in which she is.

To help a little when it comes to calculating the probable date of delivery and to be really clear when a woman is pregnant, we offer you a pregnancy calculator that, as of the date of the last rule, tells us when it is estimated that the baby is born, what was the probable date of conception, the weeks it takes for gestation, as well as how many weeks are left. All these calculations are more or less easy to perform, although it can always be good to have a pregnancy calculator on hand like this one that you have below:

How the pregnancy calculator works

As you can see it is a simple online application in which you must enter what is the date of the first day of your last menstruation. Once written down, the pregnancy calculator offers you the answers we have discussed, making an estimate of the pregnancy, saying, more or less, what was the date of conception of the child and what the probable date of delivery .

Nagele's rule

A pregnancy lasts approximately 280 days, equivalent to 40 weeks of gestation. Knowing this data can make an estimate by performing the calculation with the so-called rule of Nagele, which we have spoken on other occasions in Babies and more . It is a formula that consists of subtracting three months and adding seven days to the date of the last menstruation (the first day of the rule). For example, if the date of the last rule was February 1, 2011, we subtract three months (November 1, 2010) and add 7 days to know the probable date of delivery (FPP), which will be on November 8. Well, the pregnancy calculator that we offer you is based on these data and that is why it will offer you the result that I would give you if you made the formula.

In any case, as we have mentioned in Babies and more, the likely date of delivery should be called the unlikely date of delivery, because very few women actually give birth that day and therefore the results of the pregnancy calculator should always be taken as an approximation to the day of your new motherhood and not as a "binding contract".
