Overview
Month 3 closes the first trimester. The embryo officially becomes a fetus, the risk of miscarriage falls significantly, and for many women nausea begins to ease by the end of the month. This is also the time for important screening tests.
Your baby this month
Your baby grows from about 2 cm to around 7 cm. All major organs have formed and begin to mature. Fingers and toes separate, nails and tooth buds appear, the kidneys start producing urine and reflexes develop.
Your body this month
Your uterus rises out of the pelvis and a small bump may appear by the end of the month. Headaches, visible veins, constipation and mood changes are common; energy often starts returning around week 13.
