Pregnancy Term And Due Date
The word pregnancy is used to describe a woman’s state over a period of 9 months. During this 1 or more offspring develops inside of a woman. Usually birth of a child occurs 38 weeks after conception or about 40 weeks from the last menstrual period. According to the World Health Organization a normal pregnancy of a woman can last between 37 and 42 weeks.
When a woman visits gynaecologist or obstetrician for the first time the doctor usually provides an estimated date which is based on a sonogram when the child will be born or which is also called the due date, this due date can also be estimated on the basis of a person’s last menstrual period.
Although the due date can be estimated with the help of a pregnancy week calculator there are other factors which influence such as age and the length of previous pregnancies, weight of the mother and still there are lot more factors which affect the natural variation in the pregnancy; terms that are yet not well understood.
Though it is possible to be confident about when a person’s child will be born. Assuming about two weeks of the due date, it is currently not possible to predict the exact date of birth with certainty.
One can detect pregnancy either by using pregnancy test or the woman herself notices a number of symptoms which include missed menstrual period, increased basal body temperature, nausea, fatigue And frequent urination.
A pregnancy test works by detecting the hormones that serve as biomarkers for pregnancy and it also includes clinical blood or urine test that detect pregnancy from 6 to eight weeks after fertilization. Clinically, blood tests are far more accurate and they can detect the exact amount of hormone which is present only during pregnancy, earlier and in smaller quantities but these tests take more time to evaluate results and are more expensive than the home pregnancy urine test kits available in the market. But this does not guarantee them that they are more accurate than a home pregnancy test and these can be potentially more costly.
It is a fairly known fact that most pregnancies last 40 weeks but there are other factors which influence this pregnancy due date. Majority Of the time expecting mothers don’t even realise that both their menstrual and evolution periods count as the first two weeks of pregnancy. While many women are not aware of their pregnancy until the first missed period. By that time they could be up to 5 weeks pregnant. This simply means that finding out the due date of delivery based on from the day you took a pregnancy test is not going to calculate your due date exactly, and also factoring a few weeks here and there for Ovulation won’t work either.
