5 Weeks Pregnant

Only a little bigger than a comma, the embryo now takes on a comma-like shape. Along its curved length, the neural tube — the start of the baby's brain, nervous system, and spine — can be seen. The bump in the middle will be the baby's heart.

The embryo is now producing hCG, a hormone that can be detected by a pregnancy test. You can know for sure: you’re pregnant! You may notice some signs of pregnancy. Common ones at this stage include sore breasts, fatigue, and mood swings.

Call your doctor or midwife to schedule your first prenatal visit. Studies show that good prenatal care helps ensure healthier pregnancies, safer labor and deliveries, and stronger babies.
