Week 35
Trimester 3Days 34+0 to 34+6
Baby is now the size of a honeydew melon
Welcome to Week 35. Your baby is now considered late preterm if born during the coming weeks. While a little more growing would still be beneficial, your baby has already made incredible progress and is becoming increasingly prepared for life outside the womb. For many parents, Week 35 feels like a major mental milestone — the due date is approaching quickly, hospital bags may be packed, and every unfamiliar sensation can make you wonder whether labor is beginning.

Frequently asked questions
Is my baby fully developed now?
Most body systems are well developed, but the lungs, brain, and weight gain continue improving right up until birth.
Is it normal to feel pressure low in my pelvis?
Yes. As the baby grows and positions for birth, pelvic pressure often increases.
Should I be worried if movements feel different?
Movements often feel different because space is limited. However, movements should still remain regular — contact your provider if you notice a significant decrease.
Could labor start soon?
Yes. Some babies arrive around this stage, although many pregnancies continue for several more weeks.
