39 weeks pregnant is how many months?
Week 39 falls in the ninth 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 third trimester (weeks 28–40).
What might you be noticing?
