Pregnancy week 6

Your baby’s development

This week a tiny heartbeat may be seen on ultrasound for the first time. The embryo is about the size of a lentil, around 0.6 cm, and its heart beats at well over a hundred beats per minute, far faster than an adult's and entirely usual. Sometimes the heartbeat cannot be seen yet because the dates may be a day or two off; this alone does not mean a problem, and your doctor may suggest a repeat scan after a few days. The neural tube keeps closing, and small buds that will become arms and legs appear. Dark pigment begins to form in the eye pits, and the nose and mouth area take shape. The brain divides into three main parts. The foundations of the liver and intestines are also laid. The embryo is still smaller than a pea, but many systems are being built in that tiny body at the same time. This quick pace continues in the coming weeks.

Changes in the mother

In week 6, symptoms rise towards their peak for many people. Nausea, vomiting, tiredness, frequent urination and strong dislike of certain smells or foods are common. Being very hungry one moment and wanting nothing the next is also usual. The volume of blood in your body starts to increase, which may explain tiredness and dizziness. Avoiding sudden standing up and resting regularly helps. Seeing the heartbeat at a first scan is a great relief for many, but not seeing it should not cause immediate alarm; your doctor will explain the next steps. Light spotting can happen, but if bleeding soaks a pad, or you have severe cramps or fever, get help right away. Your mood may go up and down in these weeks; asking for help and talking about it is not weakness. Some days everything may feel hard, and that too is a natural part of this process.

To do this week

• Plan your first ultrasound and antenatal appointment.
• Spread small meals through the day to ease nausea.
• Write down your symptoms and questions and bring them to the visit.
• Share your feelings with someone you trust.

Tip for the partner

Offer to come to the scan; hearing the first heartbeat together is unforgettable for many couples.

Nutrition tip

Ginger tea or lemon water helps some people with nausea; if nausea is severe, talk to your doctor.
