To know exactly how many weeks and/or months you need to calculate the gestational age and for this you only need to know the closure of the last period (FUM) and count in a calendar the number of weeks until the current close.
Your doctor may also indicate the correct gestational age, which is suggested by the ultrasound done during prenatal care, this signature indicates exactly how many weeks of the term and how long you will be likely to give birth.
- It is also possible to calculate gestational age by indicating only the last menstrual period.
- This will let you know how many months the week of delivery lasts and the likelihood of it closing:.
When the woman doesn’t know exactly how she had her last period, the safest way to know how many weeks of pregnancy she’s had and how close she is is:
To calculate gestational age in weeks it is necessary to record the closure of the last period (FUM) in a calendar and count from 7 to 7 days, and from there, the baby will complete a week of life.
For example: If the first day of the last period was March 11 and the pregnancy result was positive, to know the gestational age it is necessary to start counting the pregnancy from the 1st day of the last period and the day I have. Sex.
On the occasion of March 11 and Tuesday, the next lunches will be completed for 7 days, and today my baby April 16, the baby would have 5 weeks and 2 days of internment, which equates to 2 months of internment.
The calculation is done because, although it has not yet been sent, it is very difficult to define exactly when fertilization was performed, since sperm could live up to 7 days before fertilizing the egg and actually starting the expedition.
To convert gestational age from weeks to months, you should observe
The shipment usually lasts 40 weeks, but the baby can be born between 39 and 41 weeks, without any problem, however, if child labour is spontaneous until 41 weeks, the doctor may choose to start working with oxytocin intravenously.
To calculate the likely delivery time, which should be about 40 weeks after UMF, it is necessary to summarize 7 days after the UMF, count 3 months ago and after placing the next one.
For example: if the UMF was from March 11, 2014 to the first 7 days of the result until March 18, 2014, the rest should be left for 3 months because the result is December 18, 2013 and the day is short 1 year. In this case, the Birth Forecast is December 18, 2014.
This calculation does not include the specific birth of the baby as it may be between 37 and 42 weeks gestation, however, the mother is informed of the likely closures of the baby.
During each week of gestation, the baby grows about 1 to 2 cm and is about 200 g long, but during the third trimester it is easier to notice this growth because the fetus has the body formed and the body of the soil so that it can focus mainly on the accumulation of thanks and prepare for the time of birth.
