Stages of Pregnancy Week by Week
Pregnancy Week 3
Find out how your baby is developing in week three and learn the early signs of pregnancy, along with the importance of choosing the right doctor.
Watch Your Baby's Growth
Something magical is about to happen! Watch as the ovulation process occurs, and then millions of sperm swim upstream on a quest to fertilize an egg.
Your Changing Body
You may experience some light vaginal bleeding when your egg implants, which many women mistake for a period. In fact, spotting that's lighter than your usual menstrual flow is one of the early signs of pregnancy. Do give your doctor a call, however, if the bleeding is fairly heavy or you experience abdominal pain, like a sharp stabbing in your pelvis or even mild cramping on just one side.
Your Developing Baby
Amazingly, your child's sex and all of her inherited genetic characteristics -- such as eye color, hair color, skin, and body type -- have been set since the moment of conception. Your developing baby, now called a zygote, has 46 chromosomes -- 23 from you and 23 from your partner. These chromosomes help determine your baby's sex and traits such as eye and hair color, and, to some extent, personality and intelligence.
Tip of the Week
Get yourself a good doctor -- pronto! Having a healthcare provider you like and trust is key. After all, this is the person who will guide you through your entire pregnancy, labor, and delivery, along with the millions of questions, tests, and emotional ups and downs along the way.
