Week 18
Second Trimester

What happens to me?

Sleeping may be increasingly difficult now, as your body continues to grow. Try propping yourself with pillows to find a better sleeping position or use a full-length body pillow to make you more comfortable. You might also try doing pelvic tilts (ask your doctor) before bed, and always be sure to go to the bathroom before lying down.

With the help of a special stethoscope, you can hear the baby’s heartbeat. On days when you are worried about how your pregnancy is progressing, hearing the heartbeat lets you know that the baby's developing and growing. For times when boredom strikes and you feel as if you will be pregnant forever, it can be a reminder that the baby is making quick progress.

Because your growing uterus has shifted your center of gravity you may be feeling a bit off balance. You should walk carefully and wear low-heeled, comfortable shoes.

How much will I be showing?

Your uterus is about the size of a cantaloupe and can be felt about 1 inch below your belly button. Your total weight gain should be around 7-11 pounds although this can vary widely. Remember that you still have over half of your pregnancy left so you will be gaining more weight. Gaining too much weight however can make the pregnancy and delivery harder on you.

What happens to baby?

The pads of the fingers and toes are formed, and the fingerprints are fully developed. The baby’s skeleton is mostly rubbery cartilage, which will continue to harden (ossify). A protective substance called myelin slowly begins to surround the spinal cord.

How big is the baby?

The baby is now nearly 5 1/2 inches long and weighs approximately 5 1/2 ounces.

Tip of the Week

While you can continue to exercise during your pregnancy, you must be more careful since your body has changed and your balance may be off!
