Why is it important to know your exact pregnancy week?

How far along you are determines nearly everything in your pregnancy including blood tests, ultrasound examinations, and more importantly when you can expect your baby to be born.  It also helps 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.
