Due date calculator By: jason caney
A pregnancy due date calculator is not an accurate method to estimate the day your baby will born. The basic logical behind this is to predict the due date according to the date you conceived. You can also use a due date calculator in backward. For example if you know the duration of your pregnancy until this day, you can use the pelvic test to predict the date of conception. Due date calculator can be very useful for women who are irregular. All you need to know is the day of your last menstrual period.
There are lots of websites on the internet that dedicated to the question: “what is my due date?” some are very simple and some very complicated. The best answer to this question is to be aware to your pregnancy development. There are different step in every pregnancy which can give you clues. For example morning sickness is a symptom that occurs only in the first trimester of the pregnancy. Knowing when you enter to the third trimester will help you to prepare better to the birth day.
Don’t be disappointed or too surprised – as stated before the due date calculators give only obscure picture, so if you passed the day your baby should be born (according to the due date calculator) don’t be too nervous about it, it will take few more days but eventually it will happen. And if you conceived before that day, it’s also natural as the average pregnancy last 40 weeks.
Giving a birth is a very exciting experience and some factors such as the exact due date will still remains a mystery.
Due date calculators are generally considered accurate within 7 days. Typically, most practitioners don't adjust due dates in either direction if the discrepancy between the two possible dates is less than 7 days. And that's true even of early ultrasounds.
There are generally two ways of measuring a pregnancy, LMP (last menstrual period) and gestational. Most due date calculators go by LMP, which calculates a pregnancy at 40 weeks or 10 lunar (4 week) months. LMP would mean that ovulation took place in your 2nd week of pregnancy (day 14). Gestational starts from the date of ovulation resulting in a 38 week pregnancy. So if you know the date of ovulation you can calculate where you are by either LMP or gestational.
The ultrasound technology may give you an odd date because they may not use either of these; they sometimes take the rate of development and change the due date based on where on their scale the baby is. The Doctor may even move the due date based on this, even if you know absolutely when the baby was conceived!
Babies only have so much possible size variability throughout pregnancy and so most will be of a certain size at a certain point in the pregnancy. The later in the pregnancy you are the more individual variability among babies there is and so the less accurate the size and date estimate will be. However, for example, almost all babies will be 2 inches at 13 weeks (LMP) and each little bit bigger than that they are, an extra day would get tacked on to an ultrasound estimate.
The solution is to calculate the due date and then, unless there are complications be ready early but figure on going late. Many people have their hearts set on their due date and are so ready on their due date that when it goes by and nothing. They get pretty upset.
