Pregnancy Week 12

Pregnancy week 12 is an important milestone. You are approaching the end of the first trimester, and many people begin to feel more confident and hopeful as the risk of early pregnancy complications decreases.

Baby Development at Week 12

What Does the Baby Look Like at Week 12?

At pregnancy week 12, your baby is about the size of a lime. Facial features are becoming more defined, with eyelids formed and ears moving closer to their final position on the head.

The baby’s organs are mostly formed and will now focus on growth and maturation. The digestive system begins practicing movements, and the kidneys start producing urine. Fingers and toes are fully separated, and tiny fingernails may begin to form.

Your Body at Week 12

Hormone levels may start to stabilize, which often brings relief from nausea and extreme fatigue. However, some people still experience lingering first-trimester symptoms.

Your uterus is growing and moving upward into the abdomen, which may reduce bladder pressure. You might notice slight weight changes, improved energy, or subtle changes in appetite.
