5 Pregnancy calculator methods
In order for a pregnancy due date calculator to be accurate you must supply some information that is rather difficult to nail down. The date of conception is needed for some pregnancy calculator due date methods. The reason that this is hard to nail down is because a healthy average woman only has one 5-day period per month in which she can get pregnant. This usually starts 12 to 16 days before her period. With these variables it is difficult to determine the exact day.
There are a number of pregnancy calculator methods that may be used and we will now outline them to you and how they work. Now we can get into the 5 pregnancy calculator methods that we can use to find your due date.
Due date by conception date
If you know the approximate conception date of your baby this can give you the due date by adding 266 days. As we said above the actual conception date can be hard to determine exactly due to the variables involved.
Naegele’s rule
To discover the approximate due date for your baby:
- Find out the first day of your last menstrual period (LMP) before you found out you are pregnant.
- Naegele’s Rule is a standard way of calculating the due date. According to it, the due date is estimated from the first day of your LMP by adding one year, subtracting three months, and adding seven days to that date. For example, LMP = 2 February 2016, +1 year = 2 February 2017, −3 months = 2 November 2016, +7 days = 9 November 2016. Then your due date is 9 November 2016.
Basal body temperature and Luteinizing hormone (BBT/LH)
Somewhat more complicated than the other pregnancy calculators the BBT/LH method is based on tracking Basal Body Temperature along with Luteinizing Hormone to discover the ovulation date and then adding 266 days.
Last menstrual period or LMP
Last Menstrual Period (LMP) is yet another fairly easy method to finding the approximate due date for your baby. Simply find the first day of your last menstrual period before you found out that you are pregnant and add 280 days from that date on your calendar. Pregnancy usually takes about 280 days (40 weeks). This method fits women whose menstruation is regular and menstrual cycle is 28 days or around.
Ultrasound method
If you can not remember the date of your last menstrual period, visiting a doctor maybe a good choice for you. You can make an appointment and your doctor may order a vaginal ultrasound to accurately determine your due date.
Ultrasound is valuable in many aspects of medicine and is probably the most accurate of the pregnancy calculators and is based on observing the baby inside the womb to determine its level of development. Your doctor will give you an approximate delivery date.
All of the methods that we have discussed can be used to find an approximate due date but none can be exact.
Another calculator that you may want to use is a pregnancy weight gain calculator to ensure that you are gaining enough weight to ensure that you baby is healthy yet not so much that it will be difficult to lose or might endanger either yours or your baby’s health.
Stay healthy for both you and your baby.
