One of the first things that a woman does when she suspects she might be pregnant is try to calculate the baby’s due date. The easiest way to determine your due date is by using a pregnancy week calculator. These can be found for free online on pregnancy and parenting websites.  Because you can find so many calculators online it’s noteworthy to point out they may yield different results.  With these thoughts in mind I put together 3 pregnancy calculators you can check out from the following reputable sites.

About.com has an excellent pregnancy and childbirth guide on their website. That guide includes a pregnancy week calculator. The calculator will provide you your due date based on the date of your last menstrual cycle and it also has a well-organized week by week pregnancy calendar. It outlines the entire 42 weeks of pregnancy, with clickable links to get images, illustrations, and in-depth information for that week.

Babycenter.com is an excellent website for expecting mothers or women who are trying to conceive. The website is filled with useful information and resources. They also have an excellent pregnancy week calculator that will give you your child’s due date, a free weekly planner, and regular e-mails with updates regarding your child’s development. It also has a number of other tools like an ovulation calculator and a baby name finder among many others.

Babiesonline.com is a really fun site for expecting moms. It has a really unique pregnancy week calculator that is easy to use and provides lots of fun information. The pregnancy calculator on this site tells you the basic info you are looking for like your conception date, due date and age of your baby. However, it also tells you some fun birthday facts about your baby like their birthstone, flower and astrological sign. Plus, it calculates the year your baby will start kindergarten, graduate high school and when they will likely finish college.

Pregnancy week calculators are a dime a dozen online, but not all of them are accurate. The three listed above provide accurate information about your pregnancy based on the date of your last menstrual cycle. In addition to that, they are attached to useful websites that you can frequent for information, support and pregnancy resources.

There are a few other websites of note that have pregnancy week calculators along with useful information. Those would include  pregnancyweektoweek.com, babyzone.com, mayoclinic.com, justmommies.com and healthatoz.com.

I hope you find these resources useful throughout your pregnancy.
