Different Ways Of Counting The Age Of Pregnancy You Can KnowVarious
techniques on how to calculate the gestational age both manual and use
of technology will provide results that will not be much different in
determining your gestational age. In this article we will present how to calculate gestational age in a
week because health professionals both midwives and doctors will do the
same in terminating your pregnancy.
1. Calendar Method
How to calculate the age of first and most simple pregnancy is to use the calendar method. The actual calendar method is how to calculate pregnancy by taking into account your First Day of Menstruation (HPHT). With this calendar method you can estimate how old your pregnancy in a matter of weeks by using correction factor.
How
to calculate it is not so difficult is to determine in advance when the
date of your HPHT, then estimate how the gestational age in a week by
reducing the mother's time checked with HPHT time and then the result
added correction factor. Correction
factors for this calendar method calculation include correction factor
0-2 months 0, correction factor gestational age 3-5 weeks 1 week,
correction factor gestation 6-8 months 2 weeks and for pregnancy 9
months and above correction factor. Added is 3 weeks.
Example
of calculating the age of pregnancy with the calendar method is as
follows, a mother came for a pregnancy examination on July 16, 2016 with
HPHT on April 10, 2016. The first estimate of maternal pregnancy at the
time of examination is 3 months 6 days, then within weeks of pregnancy this mother is 12 weeks. The correction factor that needs to be added at 3 months of gestation
is 1 week, so in other words the estimated age of pregnant women is
13-14 weeks.
And how to calculate gestational age calendar method is also used to calculate the estimated delivery time. This is done using a formula that is Naegele Formula. The
trick is to determine the date of HPHT pregnant woman and after that
menstruation plus 7, menstrual month minus 3 and menstruation year plus
1. Easy is not it? That's how to calculate the estimated delivery of Naegele formula is
only recommended for those who have a normal menstrual cycle 28 to 30
days before pregnancy.
If
we want to estimate when the estimated births of women above who have
HPHT on April 10, 2016 then the HPHT date plus 7 to 17, then the HPHT
minus 3 to 1 (April is the 4th month) and the year plus 1 to 2017 From
these results then it can be estimated the estimated date of birth of the mother with HPHT April 10, 2016 is January 17, 2017.
2. Method of examination of the uterus
How to calculate the next gestational age is to use the healthcare skill in examining your uterus. The part of the uterus used as a reference is the top of the uterus
(uterine fundus), after examining your stomach, a health worker
estimates the gestational age range based on certain medical references.
The
reference used is the pubic bone (pubic bone), if your uterus height is
around this bone then your pregnancy estimate is 12 weeks. If
the size of the uterus is larger then it can be used size 2 fingers of
this pubic bone with an estimated increase of 2 fingers of the uterus
means gesta age increased 2 weeks. Like 2 fingers above the pubic bone marks 14 weeks, then the next 2 fingers 16 weeks later.
If
the uterine peak is in the umbilicus area, the estimated gestational
age is 20 weeks and if the uterine peak is already at the lower end of
the breastbone (ulu hati), the estimated age of your pregnancy is 36
weeks. Method of examination of the rahi
