Week 20
Trimester 2Days 19+0 to 19+6
Baby is now the size of a banana
Congratulations. You have reached Week 20 and are halfway through a typical 40-week pregnancy. The positive test may feel like yesterday, yet your baby has already grown from a single cell into a tiny human with working organs, active movements, and a unique personality beginning to emerge. Many mothers are now feeling regular movements, and the growing bump makes pregnancy increasingly visible to the world.

Frequently asked questions
Am I really halfway through pregnancy?
Yes. Week 20 marks the halfway point of a typical 40-week pregnancy.
Should I be feeling the baby every day now?
Many mothers feel movement daily by this stage, although patterns can still be somewhat irregular.
Can my partner feel the baby move?
Possibly. Some babies are strong enough now that movements can occasionally be felt from the outside.
Why is my belly button changing?
As the uterus expands, the growing abdomen can cause the belly button to flatten or become more prominent.
