Week 9 Pregnancy

First Trimester

You are 9 weeks pregnant and in your first trimester. Your baby is about the size of a cherry. This week's key development: All the Essentials. NHS note: Your midwife will give you your maternity notes (often a green folder or digital app).

Baby's Development

Your baby is about the size of a cherry.

All the Essentials — All essential organs are now forming. Your baby has earlobes, a tiny nose, and even taste buds beginning to develop. The heart has divided into four chambers and is beating around 170 times per minute — nearly twice the rate of yours.

Your Symptoms

  • Visible veins on breasts and legs
  • Headaches
  • Weight gain or loss (due to nausea)

Every pregnancy is different. You may experience all, some, or none of these symptoms — and that's completely normal. If anything concerns you, speak to your midwife.

NHS Appointments

Your midwife will give you your maternity notes (often a green folder or digital app). Keep these with you at all times.

Practical Advice for Week 9

Nutrition

  • Continue daily folic acid and vitamin D.
  • Eat iron-rich foods regularly — lean meat, dark leafy greens, fortified cereals.
  • Pair iron-rich foods with vitamin C to boost absorption.
  • If nausea is easing, start reintroducing a wider variety of nutritious foods.

Exercise

  • Continue your exercise routine with any modifications your midwife suggests.
  • Aqua aerobics classes for pregnant women are available at many UK leisure centres.
  • Stretching your calves before bed can help prevent leg cramps.
  • Don't start intense new exercise regimes — now is about maintaining, not pushing.

Wellbeing

  • Visible veins on your breasts and legs are normal — your blood volume is increasing.
  • Headaches can be common — paracetamol is safe, but avoid ibuprofen.
  • Wear a supportive bra as your breasts grow and change shape.
  • If you're feeling emotionally fragile, that's the hormones — be gentle with yourself.

Preparation

  • Keep your maternity notes with you at all times from now on.
  • Your midwife may give you a 'green notes' folder or access to a digital app.
  • Research your local hospital's maternity ward — some offer tours.
  • Start thinking about who you'd like as your birth partner.
