Your body undergoes dramatic changes in the first 12 weeks. Here is what is happening and how to cope.

First Trimester: What to Expect (Weeks 1–12)

The first trimester is a period of rapid development. By week 12, your baby has all major organs forming, a beating heart, and is about the size of a plum.

Common Symptoms

  • Morning sickness: Nausea affects up to 80% of pregnant women, typically peaking around weeks 8–10
  • Fatigue: Progesterone surges can make you feel exhausted
  • Breast tenderness: Hormonal changes prepare your body for breastfeeding
  • Frequent urination: Your growing uterus puts pressure on the bladder

Key Milestones

  • Week 6: Baby's heart begins to beat
  • Week 8: Fingers and toes start forming
  • Week 10: All major organs are developing
  • Week 12: Risk of miscarriage decreases significantly

Tips

Eat small, frequent meals to manage nausea. Stay hydrated and rest when needed. Schedule your first prenatal visit around weeks 8–10.
