Week 12 · First trimester
Week 12, gently.
Your baby is the size of
a plum
- 5.4 cm long
- 14 g
Your baby now has fingerprints — unique, already, before anyone has seen their face.
“Fingerprints, already, before anyone has held the hand.”
What’s happening inside
Fingerprints form this week — a pattern unique to this person that will be theirs for life. Reflexes emerge: the baby can curl fingers, squint, and move gently.
How you might feel
Your uterus is rising out of the pelvis and into the lower abdomen. You may be starting to show, especially if this is not your first pregnancy.
