21 Weeks Pregnant
By the time you are 21 weeks pregnant, you are halfway through your pregnancy. Your baby is now about 7.2 inches long, and his or her tissues and organ systems are continuing to mature. For most women, pregnancy becomes easier by the time they are 21 weeks pregnant. With your doctor's permission, you may now want to do some low-impact exercise, such as yoga or walking. Mild exercise can be helpful in alleviating symptoms like backache and varicose veins.
Congratulations! You are halfway through your pregnancy. At 21 weeks pregnant, your baby now measures about 7.2 inches and weighs about 10.5 ounces. Although your baby's growth rate is slowing down during week 21, the organ systems continue to mature.
