You're to 21 weeks pregnant! At your prenatal appointment your provider has probably been measuring the height of your uterus (fundal height) since it appeared above your pubic bone. After about 20 weeks pregnant, this measurement generally correlates with your due date. Fundal height measurements assess growth from visit to visit. Ultrasound would be performed for any inconsistency in fundal height. After about 36 weeks the measurement for fundal height becomes less accurate as your baby settles into your pelvis.
As your pregnancy progresses, you're carrying more weight. Because this is pregnancy weight, it changes your center of gravity. You may feel clumsier, and lose your balance much easier. Be careful! Take extra precautions to make sure your steps are sure and steady. This is the time you start taking things slower, for yours and your baby's safety.
Weight gain is on many pregnant women's minds; make sure you discuss this with your doctor. While you don't want to obsess, you also don't want to let your weight get out of control, risking complications. Weight gain is also a way for your doctor to decide if you are measuring right for your due date, and can monitor your baby's growth.
You may be finding yourself out of breath more often; this is caused by your uterus pushing against your diaphragm, leaving less space for your lungs.
Your baby could measure about 10 inches from head to toe and weighs about three-quarters of a pound. The eyebrows and eyelids are fully developed and the fingernails cover the fingertips. Babies are more active at this stage, as they still have lots of room to move around. You'll feel a lot more movement from your little one.
