34 weeks pregnant is how many months?
At 34 weeks you are in the 8th month of pregnancy, within the third trimester. The conversion uses the real average of 4.345 weeks per month, which is why "4 weeks = 1 month" only works as a rough guide early on.
Your baby at 34 weeks
The lungs are nearly ready and the baby drops toward the pelvis. Around now, the size is comparable to a cantaloupe.
