Few things can compare to the rush and excitement of when you take a pregnancy test and read out the positive result! Once you've processed the news that you're going to be a mom, your thoughts will naturally turn to planning and one of your first questions will no doubt be: when is my due date?

Here's how to use pregnancy calculator to see how many weeks pregnant are you from your last period. With these three simple steps you can calculate your how far along are you and the due date by using Bumpies pregnancy due date calculator:

  • Figure out when was the first day of your last period or your date of conception.
  • Enter the relevant dates into the pregnancy week calculator.
  • Then hit Find out now! to find out your expected due date. Keep in mind every pregnancy is unique and the result will be an estimation rather than a fixed date.

While it's true that most pregnancies last 40 weeks, other factors at play will determine your pregnancy's due date. Most expectant mothers don't realise that both menstrual and ovulation periods count as the first two weeks of pregnancy. Many won't be aware of their pregnancy until their first missed period, and by that time they could be up to five weeks in.

Unless you can pinpoint exactly what point of your ovulation cycle you were in at the time of fertilisation, it's difficult to know how far along you are and what date you'll meet your baby. Luckily, our EDD calculator can help. Using both the date of your last period and the length of your regular cycle, or the exact date of conception, our pregnancy calculator will quickly work out your estimated due date, tailoring it accordingly for longer, shorter, and average cycle lengths.

A pregnancy calculator makes it easy for you to calculate your pregnancy week. By simply feeding some basic information, like the first day of your last menstrual period or your conception date into the pregnancy calculator, you can get an estimated due date (EDD).

Today, there are several traditional methods and new-age due date calculators through which you can figure out when your baby will make a grand entrance.
