Your baby this week

Your uterus has roughly doubled in size. You might not look pregnant yet, but you may feel bloated and notice your waistbands getting snug.

Common symptoms at week 7

  • Excess saliva
  • Food aversions
  • Fatigue
  • Mild cramping

This week’s tip: Aversions are normal — eat whatever stays down. Bland, cold foods often go down easier than hot, strong-smelling meals.

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.
