First trimester

6 Weeks Pregnant

Early changes

This week your baby is around the size of a lentil.

How your baby is developing

  • Early development continues quickly on a very small scale.
  • Tiny features are gradually beginning to take shape.

What may be happening in your body

  • Nausea can become more noticeable now, and despite the name it may come and go at any time of day.
  • A sharpened sense of smell can turn everyday odours — coffee, cooking, perfume — suddenly overwhelming.
  • Breasts may feel fuller, heavier, or sore as they continue to change.

How you may be feeling

  • Feeling unwell while there's nothing to show yet can be disorienting and hard to explain to others.
  • Some people feel thrown that symptoms arrived before they'd fully taken in the news.
  • On rough days it's understandable for low mood or worry to creep in.

Worth remembering

Morning sickness comes and goes differently for everyone, and often eases later on.

A closer look

Nausea and a sharper sense of smell

Around six weeks, nausea and a heightened sense of smell are among the most common early symptoms, and the two often go together since strong smells can set off queasiness. It's widely called morning sickness, but for many it isn't limited to mornings. For most people it eases as the first trimester goes on, though the timing varies a lot.

When you feel rough but don't look pregnant

Coping with nausea and tiredness while your pregnancy is still invisible to everyone else can feel isolating, and this can be an emotionally stressful stretch. Some people notice anxiety or low mood alongside the physical symptoms. Some find that talking with someone close helps lighten it.

Something you can do this week

Small, frequent snacks and rest help some parents through early queasiness.

What comes next

Symptoms often build a little more over the next few weeks before settling.
