35 weeks

How your baby's growing: Your baby's getting big. He weighs a tad over 5 pounds and is just over 18 inches long. Because it's so snug in your womb, he isn't likely to be doing somersaults anymore, but the number of times he kicks should remain about the same. His kidneys are fully developed now, and his liver can process some waste products. Most of his basic physical development is now complete — he'll spend the next few weeks putting on weight.

How your life's changing: Your uterus — now up under your ribs — has expanded to about 15 times its original volume, and you may feel like you've run out of room! If you could peek inside your uterus, you'd see that there's much less amniotic fluid and much more baby in there now. Your ballooning uterus is crowding your internal organs too, which is why you probably have to urinate more often and have heartburn and other digestive problems. If you don't have these problems, you're one of the lucky few.

Your doctor or midwife will probably want to start seeing you every week until you deliver. She may ask you to count fetal movements, to track your baby's activity level.
