Pregnancy Week 27: The Final Week of the Second Trimester
Pregnancy week 27 marks an important milestone because it is the final week of the second trimester. As this stage ends, your baby continues growing quickly and preparing for the final months of development before birth.
Many women begin noticing stronger baby movements during this time. Kicks, stretches, and rolling sensations may become more noticeable as your baby becomes stronger and more active inside the womb.
This stage can also bring a mix of excitement and anticipation as you prepare to enter the third trimester. Your body continues adapting to support your baby’s growth while preparing for the final stage of pregnancy.
Baby Development at Week 27
At twenty-seven weeks pregnant, your baby is about the size of a head of lettuce and continues growing steadily each week.
Your baby’s brain is developing rapidly during this stage. The brain is becoming more complex as new nerve connections continue forming, helping control movement, senses, and future learning.
Your baby’s lungs are also continuing to mature. Although they are not yet fully developed, important progress is being made as the lungs prepare for breathing after birth.
Your baby’s eyes may now open and close, and the baby can begin responding to light. If a bright light shines toward your abdomen, your baby may move or react.
Your baby’s hearing is also improving. Sounds from outside the womb, including voices and everyday noises, can reach your baby. Many babies become familiar with the sound of their mother’s voice during pregnancy.
Fat is continuing to develop beneath the baby’s skin. This helps the baby’s body become more rounded and prepares the baby to regulate body temperature after birth.
Common Symptoms During Week 27
Common experiences during week 27 include:
Back pain
Swelling in the feet or ankles
Sleep changes
Strong baby movements
Occasional leg cramps
As your baby grows larger, pressure on muscles and joints may lead to mild back discomfort. Swelling in the feet or ankles may also occur due to increased blood circulation during pregnancy.
Sleep changes are also common at this stage. Many women find it harder to sleep comfortably as the abdomen grows and certain sleeping positions become less comfortable.
These symptoms are a normal part of pregnancy as your body prepares for the final trimester.
Changes in Your Body
Your uterus continues growing upward and may now be several inches above your belly button. As your abdomen expands, your center of gravity may shift slightly.
This change in balance may affect posture and sometimes contribute to back discomfort.
Your body is also increasing blood volume to support your baby’s development. This increased circulation helps deliver oxygen and nutrients to your baby through the placenta.
Some women may also notice their baby bump becoming more noticeable as pregnancy progresses toward the third trimester.
Preparing for the Third Trimester
Week 27 is a good time to begin preparing for the third trimester. Many parents begin focusing more on final preparations for their baby’s arrival.
This may include organizing baby essentials, preparing a sleeping space for the baby, or learning about newborn care and feeding.
Taking time to prepare early can help reduce stress later in pregnancy.
