The lungs can now make breathing movements, while the organs continue maturing. Fat is filling out folds in the skin as your baby grows.
27 weeks pregnant is how many months?
Week 27 falls in the seventh month of pregnancy. Weeks and months don’t divide evenly, and your antenatal care counts in weeks — so Zohra keeps weeks, and prints the month for the relatives who ask.
That puts you in the second trimester (weeks 14–27).
What might you be noticing?
A tired week. fatigue may be more noticeable now.
A stuffier night. snoring can become more common because nasal passages may be swollen or blocked.
Everyday changes. heartburn, leg cramps, backache, and feeling hot are listed among common symptoms.
