The doctors predict the time of a pregnancy by weeks, since it is a much more precise formula when calculate almost the exact and approximate number of days. Mothers need this data by calculating the pregnancy by months, but some mothers want to know how to know how many weeks pregnant they are.
There is a subtle tool to control the exact or total moment where the pregnancy is. It is necessary to know specific data such as the exact day of the last period (FUR) and thus make the prognosis much better, on what day you are in the pregnancy and when you can get out of accounts.
How to calculate how many weeks pregnant I am?
To calculate the exact week in which you are pregnant, take as a starting point the last day is that she had her period or menstruation. From here, the weeks that have elapsed up to the current date are counted.
It is a calculation that approximates the days approximate in which a woman can be pregnant, although it is not exact, since it cannot be determined when was the day it was conceived. An example can be: the day that your period does not come down and when you already calculate that you are pregnant, approximately 4 weeks. Although it could be that conception occurred two weeks earlier.
But it may be that yes, the key day is known or because they performed an in vitro fertilization, in this way the date will be formalized much better. In this way, both midwives and obstetricians use this data to calculate the exact moment where your pregnancy is.
On the one hand, it is counted when it arrives the 12th week of pregnancy so that the first ultrasound can be taken. In this way, the measurements of the fetus are taken and exact data is taken as to whether everything coincides and evolves normally. On the other hand, the date of the last day of the rule is taken to determine when will be the exact date of delivery.
How to calculate the date of delivery?
From the last day of the rule add 280 days to calculate the day of delivery. A few small details should be taken into account, because if your rule does not have an exact 28-day cycle, that can modify the data.
For example, if your period lasts 27 days, you have to subtract 10 days from the 280 days expected. Even if your period lasts more than 28 days, you will have to add those extra days, instead of subtracting.
What is a gesture?
The gestogram is a calendar that is used to calculate the weeks of pregnancy. It is also known as the pregnancy wheel and is used by midwives and gynecologists to determine where you are in your pregnancy to track more accurately. In this way, it will be possible to calculate the revisions much better and assess that each one of them coincides with the measurements and growth of the baby. It will also be of vital importance to know it so that the pregnancy do not exceed 41 weeks of pregnancy, since the placenta has an expiration date and does not work properly for longer. If so, start a induced labor.
How to convert weeks of pregnancy into months
The following data determines how to calculate from how many weeks a pregnancy is maintained within the margin of the month that represents it:
- 1 to 4 weeks: 1st month of pregnancy
- 5 to 8 weeks: 2st month of pregnancy
- 9 to 13 weeks: 3st month of pregnancy
- 14 to 17 weeks: 4st month of pregnancy
- 18 to 22 weeks: 5st month of pregnancy
- 23 to 27 weeks: 6st month of pregnancy
- 28 to 31 weeks: 7st month of pregnancy
- 32 to 35 weeks: 8st month of pregnancy
- 36 to 40 weeks: 9st month of pregnancy
The gynecologist makes an approximate calculation of the moment of gestation in which a pregnant woman is. As we have outlined, it will serve to assess whether later in the ultrasound the calculated weeks coincide with its evolution. If these data do not coincide, the specialist can modify the date of the last rule, in most cases it could be brought forward.
