What is the next best step? You have to get more information about your baby’s condition by carefully monitoring your pregnancy.

A pregnancy calculator is one of the best tools you can have during your pregnancy. You might not even have noticed your pregnancy until your first missed period. Knowing your due date can help you be better prepared for what’s to come. You can learn more about baby calculators and their benefits in this article. To calculate your due date, it’s essential to know your conception date or menstrual period LMP. The date calculated can give you a rough estimate of when to expect the baby.

What Is A Pregnancy Due Date Calculator?

Due date calculators are a great help to technologically-savvy expectant moms. There’s no need to ask, “When am I due?” Even before going to a healthcare provider, moms already have an idea of when to expect their baby based on the information they possess. These calculators use the first day of your last menstrual period (LMP) to calculate the expected delivery date, considering that most pregnancies last about 40 weeks. However, remember that this tool provides an estimate, and your doctor or healthcare practitioner might determine a more precise due date during an ultrasound, which is part of the diagnosis process. According to the American College of Obstetricians and Gynecologists, this method is commonly used because it’s easy and based on observable events. However, ultrasounds and other methods healthcare practitioners perform may provide a more accurate date as they calculate based on the baby’s development.

Using a pregnancy calculator is relatively simple. You will just have to enter the last date of your menstruation into the appropriate field, and it’s as easy as that. You will also need to enter your cycle length. The average length is 28 days, but not all menstrual cycles are the same. The tool then does all the calculating for you. All the relevant information you need will appear on the screen after just a few seconds. You will find more helpful guides here at BabyCenter.com.

You can also use a different calculation method. If you happen to know the date you conceived, you can compute your due date using the date of conception instead of your last menstrual period. However, very few women know their actual date of conception since sperm can live in your fallopian tubes for up to five days. If you’ve conceived via IVF, you can figure outd your due date based on your IVF transfer date. Many pregnancy calculators have an IVF option that you can select. Entering the correct information is important to accurately date your pregnancy timeline.

Pregnancy Calculators Help You Know Your Due Date

You will be able to level your expectations when you are aware of your exact due date. Due date computation can help mothers with no access to healthcare providers know when to expect their baby. Even after visiting a midwife and getting a blood test and physical exam, using a pregnancy calculator can give you an accurate estimate of when you should deliver your baby.
