18 Weeks Pregnant

As you continue on into the second trimester, you will start to notice that your appetite is increasing. This will happen over the remainder of your pregnancy. As the baby grows, he or she will be absorbing the majority of your nutrients. As that happens, your appetite increases. This can be where women get into trouble with gaining weight. You will have to increase the amount of food that you eat, but try to keep it healthy. It isn’t always easy, but try to steer clear of the unhealthy foods and eat those less frequently.

Baby’s Development

By now the baby’s CR, or Crown to Rump length should be approximately 5-1/2 inches and the baby will now weigh around 5.25 ounces. The baby is developing a few layers of fat, but this growth will slow down for a bit. In the last month or so, the baby will gain about ½ a pound every week.

Around this week or perhaps before, your doctor will be able to listen to your baby’s heartbeat with an abdominal Doppler.  The familiar whooshing will be checked with each doctor’s visit.

By now, your baby could be doing somersaults in the uterus and can even sit cross-legged. The baby’s hearing is more advanced, and they can hear sounds as well as the sound of your voice. If they become startled, they may start kicking. The baby will become familiar with the sound of your heartbeat and familiar voices. The blood continues to go through the umbilical cord.

Baby can flex his or her arms and legs with more strength now. The genitals have fully formed, but finding out if you are having a boy or girl won’t usually happen for a few more weeks.

Changes With Your Body

By now you will be able to feel the uterus in the lower part of your abdomen. At week eighteen the uterus is about the size of a cantaloupe. You may also start to use the bathroom more often as the baby will at some point be putting pressure on the bladder. Other symptoms moms have reported include

  • Dizziness
  • Vivid, strange dreams
  • Increased appetite
  • Increased sex drive
  • Backaches
  • Swelling

What To Expect

Coming days will leave you feeling pretty well overall.  Take this time to enjoy your pregnancy, keep a journal and make sure to pay attention for your baby’s movements.

To keep up your energy, you want to snack more often during the day, but stay away from empty calories.


Keep taking your prenatal vitamins and stay hydrated. Relaxing and enjoying the pregnancy is the best thing that you can do right now. Keep following your doctors’ advice and get plenty of rest. If you want to start looking at baby names, it can be a fun way to pass the time as well.
