17 weeks pregnant

Size: 7 inches (18 cm)

Weight: 5 ounces (150 grams)

"If I am not asleep, sometimes I kick hard against the wall of the uterus. I feel like I am getting bigger and bigger."


Your baby's weight has doubled in two weeks and now weighs about 3.5 ounces! The crown-to-rump length of your growing baby is 4.4 to 4.8 inches. If you spread your hand out opened wide, you can see about how big your baby is.

Your uterus is moving up and is now approximately 1.5 to 2 inches below your navel. You are showing more now and there is a noticeable swelling in your abdomen. At this point in your pregnancy, a 5 to 10 pound weight gain is normal. Other people can probably feel the difference in your lower abdomen if they were to rub your tummy. To be the most comfortable, you should be wearing maternity clothes or clothing that is too large for you. You may have felt your baby move already. However, you might not feel it move every day at this point. As your pregnancy progresses, movements become stronger and more frequent. Feeling your baby move can help reassure you that your baby is doing well. You might also notice that your gums or nose bleed occasionally. This is from the increased blood volume that puts pressure on small blood vessels and capillaries.

Huge changes continue to take place within your developing baby. This week fat begins to form and will continue to do so until he is born. Fat is important to the body's heat production and metabolism. Right now, at 17 weeks, water makes up about 3 ounces and fat 0.018 ounces of your baby's body. In a baby at term, fat makes up about 5.25 pounds of the total average weight of 7.7 pounds. The placenta is continuing to grow at an amazing rate. The placenta will continue to develop in tandem with the fetus and it will weigh more than a pound at birth! By this week, the placenta is large and well established with a network of blood vessels that exchange nutrients and waste.

The eyes are facing more forward. The ears are now close to their final position.

Your baby is more flexible with ability to move head, mouth, lips, arms, wrists, hands, legs, feet, and toes.

Fingerprints are forming now.

Although his eyes remain closed, through his eyelids he can distinguish between light and dark. If you lie in the sun with your naked belly your child will swim, so to speak, in a pink slightly translucent bath. If you lie under the blankets, his little house is dark. Perhaps that's why your baby will move a bit more often at night, just as if he wants to say: "turn on the light".


How your life's changing:
With more weight up high and out in front of your body, you may feel a bit off-balance as you walk around. Store away your high heels and wear low-heeled shoes to reduce your risk of taking a tumble.You're likely to feel protective of your tummy, and that's good. Trauma to your abdomen could be harmful to your baby and dangerous to you, so be sure to buckle up when you're driving. Keep the lap portion of the seat belt under your belly and very snug across your hips for maximum protection.
