Quick answer

Your body at 7 weeks

Nausea often peaks around now. Small, frequent meals and dry crackers in the morning can help. Smells may feel much stronger.

For your partner

Nausea is real and can last all day.

  • Keep crackers and water by the bed
  • Handle strong-smelling chores like the bin
  • Don't take mood swings personally

Call your doctor or hospital straight away for bleeding, severe pain, fluid leaking, severe headache or vision changes.
