4-weeks-pregnant

8-weeks-pregnant

Week 8: Your doctor may look or listen for the baby's heartbeat with an ultrasound. Once you see or hear it, your miscarriage risk drops to about 2 percent. He'll also give you an official due date—though very few women actually deliver on that day.  Read more about being 8 weeks pregnant.
