Congratulations, you are now officially half way through your pregnancy. Although the average length of gestation is 40 weeks, it is still considered within a normal range to deliver 2 weeks either side of this. At 20 weeks pregnant, you may find you are walking a little differently to accommodate that extra lump in your belly. This is because your centre of gravity is changing.<br /><br /> <br /><br />Changes in Body:<br /><br />- A yellow fluid called colostrum may leak from your breasts now.<br /><br />- The uterus is enlarging rapidly and your navel may be flattened or push out. It will stay that way until after birth.<br /><br />- Heartburn may become a problem now because the uterus is starting to push on the stomach.<br /><br />- Troubles breathing as the baby pushes against your lungs.<br /><br />- Leg cramps and swelling continues.<br /><br />- High energy and libido.<br /><br /> <br /><br />Your Baby:<br /><br />- Vernix a white greasy substance is starting to form over the fetus. This protects babies skin from the amniotic fluid, and wears off after birth.<br /><br />- Baby is now 25.5cm long and now weighs 340 grams.<br /><br />- Girls: Developing a supply of eggs.<br /><br />- Boys: Testicles have begun their descent.<br /><br />- Taste buds are working.
