what's happening in your body
Your provider may schedule the glucose screening this week. Bump is sizeable — you may feel waddly or off-balance.
gentle tips
- Do the glucose screening — it catches gestational diabetes early.
- Eat balanced meals — protein, complex carbs, healthy fats.
- Wear flat or low-heel shoes for stability.
- Strengthen your core gently with prenatal-safe exercises.
- Track kicks daily — patterns matter from now on.
what to expect next
From here on, every week added makes a survival difference. Next month brings rapid brain growth and lung maturation.
