How many weeks am I and why is it important?

Your pregnancy weeks help determine blood tests, ultrasound examinations, and more importantly when you can expect your baby to be born.  They also help you identify certain situations to learn what is normal and when to have procedures done. What is normal at 26 weeks may not be normal at 32 weeks. Also, 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 information throughout my pregnancy?

This pregnancy calculator helps you find out exactly how many weeks pregnant you are right now, details 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 weekly and daily pregnancy calendar.
