How is the Date of Pregnancy Calculated?

One of the most important questions that you start with excitement and is quite enjoyable is how many weeks pregnant you are. In this article, we also aim to inform you about calculating pregnancy week when we talk about what stages you will go through for weeks.

Contrary to popular belief, obstetricians calculate the pregnancy calendar, instead of the date of fertilization, it is based on the start day of the deadline. The date of fertilization usually falls approximately 15 days after the date you were last. However, when calculating the pregnancy week, this date is not based on the date before that. This method is based on the first day of the last menstrual history and is added to this day for 7 days and goes back 3 months.

For example, if you want to

If your deadline is November 20, 2018, we will have reached November 27, 2018 when we add 7 days to March 20. When we go back three months from November, we reach August. When we add one year to 2018, the estimated date of birth of the baby is revealed: August 27, 2019

The calculation made when creating a pregnancy calendar in the medical sense is done according to the week account, not according to the month account. The weeks of birth are usually 38. And 42. It’s weeks. Since very few births take place on the estimated dates, it is unfortunately not possible to give a timetable with precise accuracy.
