Baby's Development

The webbing between fingers and toes has fully disappeared, leaving individual digits. Fingernail and toenail beds are starting to form, though actual nails won't appear for several more weeks.

Your baby's bones and cartilage are continuing to develop, and the basic structure of all major organs is now in place — from this point forward, it's largely about growth and refinement rather than new structure formation.

Tooth buds are forming beneath the gums, and your baby's external genitals are beginning to develop, though it's still too early to determine sex via ultrasound.

Changes in Your Body

Your uterus is now about the size of a grapefruit. Many women start to notice their first trimester symptoms beginning to ease around this time, though others continue to feel unwell for a few more weeks.

  • Nausea, possibly starting to ease for some
  • Fatigue
  • Bloating and gas
  • Breast tenderness continuing
  • Visible veins on breasts or abdomen
  • Occasional headaches

Nutrition This Week

Continue focusing on folate, iron, and calcium-rich foods as your baby's development continues. Leafy greens, beans, dairy or fortified alternatives, and lean proteins are all great choices if you can tolerate them.

🧘

Safe Exercises

If nausea is easing, you may find you have a bit more energy for movement. Walking, swimming, and stationary cycling are all generally well-tolerated options at this stage.
