What's happening this week?
• The sperm and egg meet. The strongest sperm travels up the fallopian tubes to fertilize the egg. You've conceived!
• Your baby is a single cell. After it is fertilized, the egg is called a zygote. This zygote contains chromosomes, which can determine your baby's physical characteristics and, to some extent, his personality.
Pregnancy symptoms and solutions: Fatigue
The issue: Fatigue is a common pregnancy symptom due to hormonal changes in your body.
The solution: Drink plenty of water, eat well, exercise and try not to overexert yourself.
How you can help to support your body during week 3 of pregnancy
• Make sure you get 27 milligrams of iron a day. Without iron, you will feel weak and tired, especially when you're carrying a growing baby.
• Eat 46 grams of protein at this pregnancy stage. Protein makes up 75 percent of your body tissue, and will help to support your body through this period.
Mom's Tip of the Week: Include DHA and choline in your diet
DHA (docosahexaenoic acid) is a building block for your baby's brain, and choline supports the healthy development of those brain cells. Take a prenatal supplement containing DHA, and stock your kitchen with eggs and spinach, which contain choline.
