Why it's important to know your exact pregnancy week

How far along you are in pregnancy determines nearly everything in your pregnancy because it revolves around your pregnancy weeks including some blood tests, ultrasound examinations, and more importantly when you expect the baby to be born.  What is normal at 26 weeks may not be normal at 32 weeks. Tests that should be done at 20 weeks but are done at 16 weeks could be interpreted incorrectly.

How can I calculate important week-by-week dates and information throughout my pregnancy?

This pregnancy calculator helps you find out exactly how many weeks pregnant you are right now, details on your baby's development, and precisely what is happening to your body at the moment. Just enter your pregnancy due date or other information to create and calculate a personalized pregnancy calendar. The babyMed Monthly Pregnancy Calculator and Calendar is a week-by-week pregnancy calculator and calendar with information for each day of your pregnancy.

To create a Week-By-Week calendar choose from the following options:

  • Weekly Count: Follow new developments in weeks and days 
  • Daily Countup: Count up how many days you are into your pregnancy 
  • Daily Countdown: Count down your days left until your due date 
  • Fetal Weight: Available in ounces or grams
  • Ultrasound measurements: BPD, FL, HC, AC

Why is it important to know exactly what happens in my pregnancy week by week?

As you progress in pregnancy each week changes in your body and the baby become important to understand. A baby at 10 weeks is supposed to weigh much less than at 16 weeks, for example. Gaining 10 lb by 16 weeks is normal but not by 26 weeks.
