For every 27 weeks pregnant mom, this week marks your triumphant entry into the third trimester of pregnancy. You put on more weight during this period and your baby become more active. From this week onwards, various changes take place in you and your developing baby.
Your baby measurement chart changes from now, no longer measured from crown-to-rump but head-to-toe. Measuring about 15 inches from head to toe and weighing a little over 2 pounds, when you’re 27 weeks pregnant, its head is more than 2.5 inches in diameter.
Your baby’s brain and taste buds are active, and may begin to suck its fingers or thumb. It opens and closes its eyes. Your baby has eyebrows and eyelashes. The retina that allows images and light to come into focus gets fully matured this week.
At the time you’re in pregnancy week 27, your baby may start to rotate in preparation for the head down position. Your baby’s lungs have developed by this time and are capable of breathing air now. Its brain stem can regulate rhythmic breathing and basal body temperature.
Your baby sleeps and wakes at regular intervals. Its hair is growing daily as well. The network of nerves to your baby’s ears matures now, so your baby may be able to recognize your and your partner’s voice. Its muscle tone is improving and its body is getting round and fatty.
In pregnancy week 27, you’ll have gained between 15 to 20 pounds. You may feel very tired. Increased weight, difficulty in sleeping and some other factors can make you fatigued. You may experience frequent urination from this week, because your increasing uterus puts pressure on your bladder frequently. You may even get urine leakage, when you laugh or cough.
Your breast may become tender when you’re twenty-seven weeks pregnant. This is because the milk glands are developing. The breast size continues to increase and you may need to get a bigger bra.
Your uterus continues to grow and press on the diaphragm, so you may feel shortness of breath. Mood swings, sudden food cravings and Braxton Hicks contractions are very possible symptoms to expect in 27 weeks.
As your body prepares for the big day, you may start noticing other symptoms. Back pain and muscle cramps are common among them. Your increasing uterus puts pressure on the veins and nerves, which result in cramps. Your uterus pushes on the intestines and affects its ability to function properly, so you may experience constipation, indigestion and heart burn.
You need to take a well balanced diet in pregnancy week 27. Your baby is growing and its vital organs are developing. Hence, eating nutritious foods is crucial. Make sure to drink plenty of water and juice. Increase your fiber intake to avoid constipation.
Mood swings are common by the time you’re 27 weeks pregnant. You need not take them seriously. They are caused by hormonal changes and they wane as your pregnancy progresses. Shortness of breath is another common symptom during this period. You can alleviate it by reducing stress and decreasing your activity.
Your doctor may recommend you to undergo blood test to check for pregnancy anemia. If you’re anemic, you need to increase food rich in iron in your diet.
For the expecting moms whose blood group is RhD negative, your healthcare providers may administer anti-D injection as may be considered appropriate for such 27 weeks pregnant moms.
Those who are RhD positive have a protein known as D antigen on their red blood cells. RhD negative moms may need to get an anti-D injection to avoid some complications.
