Pregnancy Calculator Basics

Pregnancy calculators (also known as week by week and milestone calculators) offer a convenient tool for the pregnant woman looking to understand more about the changes that are likely to take place in the body throughout the duration of a pregnancy. An effective calculator is able to let a woman determine the trimester that she is in, when the baby might be due, and to track the milestone events throughout the course of the nine-month pregnancy.
Basically, the purpose of the pregnancy calculator is to make the often difficult task of making sense of pregnancy math a far-sight less complicated. It is often found to be the case that a common confusion in pregnancy relates to the method of calculating the gestational age. In general a pregnancy will be dated from the very first day of the last menstrual period, and not from the date of conception.
Pregnancy calculators often vary significantly in relation to the type of information they are able to offer. A pregnancy week by week or milestone calculator for instance is able to determine specific landmark events, which is perfect to keep the pregnant mother up-to-date with the most significant times throughout the pregnancy. One of the early milestones which information is provided takes place at 10 weeks, this relates to the move from embryo to fetus. Other key features that might be integrated include the 12 week mark when the baby's heart begins to beat.
In view of the fact that a typical pregnancy is expected to last 40-weeks, a week by week pregnancy calculator often matches that duration, although there are some calculators that are able to run for a length of 42-weeks, which will take into consideration the overdue baby. In general, it is the earlier weeks of a pregnancy that a woman is likely to be interested in the developments, as that is when the most significant milestone events take place.
If interested in using a pregnancy calculator with detailed information to follow along with the major changes that are likely to be experienced, then it is often possible to find a range of these tools online, which offer varying degrees of accuracy and information. It is often the case of searching the type of web sites that are aimed at the expecting mother and try to find out which of the online tools and resources are generally being recommended for use.
