Baby's Development
At 9 weeks, your baby officially transitions from being called an embryo to a fetus, marking the completion of the most critical early organ-formation stage.
Tiny muscles are developing, allowing for small, jerky movements of the arms and legs — though you won't feel any of this for many more weeks. The webbing between fingers and toes is starting to disappear as individual digits become more distinct.
Baby's heart has now divided into four chambers and is beating roughly twice as fast as yours.
Changes in Your Body
Your uterus is roughly the size of an orange now. Many women start noticing more visible changes to their breasts, and some begin to see faint veins becoming more visible as blood volume increases.
Common Symptoms
Common at 9 weeks:
- Continued nausea and fatigue
- Bloating
- Mild abdominal cramping as the uterus stretches
- Increased vaginal discharge
- Skin changes, including some early acne for certain women
Nutrition This Week
Protein-rich snacks like nuts, yogurt, or boiled eggs can help keep your energy steady between meals. If aversions are limiting your diet, try to find at least a few reliable "safe foods" you can return to.
Safe Exercises
Continue with gentle, consistent movement as tolerated. If you're new to exercise, prenatal-specific classes are a great low-pressure way to start safely.
Medical Checklist
Consider this week:
- Asking your doctor about the timeline for genetic screening tests, if you're interested in them
- Continuing to avoid alcohol, smoking, and raw/undercooked foods
- Staying consistent with prenatal vitamins
Doctor Visit Guide
Some genetic screening options, like first-trimester combined screening, can begin around weeks 10-13 — this is a good time to ask your provider what's available and recommended for your situation.
