What Does 12-Week Pregnancy Mean?

Pregnancy is calculated from the first day of your last menstrual period. At 12 weeks of pregnancy, your baby’s length reaches approximately 5–6 cm and is now about the size of a plum. This week is a critical period as your baby completes the first trimester and the risk of miscarriage significantly decreases.

All of your baby’s major organs have formed and started functioning. During this week, your baby’s intestines fully settle into the abdominal cavity, the kidneys begin producing urine, and the thyroid gland starts producing hormones. Additionally, your baby can now make more coordinated movements, suck their fingers, and even yawn.

What Happens to Your Body at 12 Weeks of Pregnancy?

At 12 weeks of pregnancy, you may continue to experience some symptoms due to changes in your hormone levels. However, by the end of the first trimester, these symptoms often begin to decrease in many women.

Tests Performed at 12 Weeks of Pregnancy

At 12 weeks of pregnancy, your doctor may recommend a first-trimester screening to measure your baby’s nuchal translucency and screen for certain chromosomal abnormalities, such as Down syndrome. This test includes a blood test and an ultrasound examination. Additionally, you can optionally have a NIPT (Non-Invasive Prenatal Test). This blood test analyzes your baby’s DNA to more accurately assess the risk of chromosomal abnormalities like Down syndrome.
