Your baby this week
Your baby can taste what you eat through the amniotic fluid, helping shape future flavour preferences. Rapid eye movements suggest they may already be dreaming.
Your body & how you might feel

This week’s tip: Moisturise your bump if it feels itchy — it won’t prevent stretch marks, but it soothes tight, dry skin.
A gentle reminder: This is an estimate, not medical advice. Dates and figures are general guidance — every pregnancy is different. Your healthcare provider’s assessment, especially from an early ultrasound, always takes priority. Always speak with your provider about your pregnancy.
