Pregnancy week 6
This week your baby is about the size of a sweet pea — around 0.6 cm and 0 g.
Your baby this week
Your baby is now about the size of a sweet pea and developing very quickly. The tiny heart has begun to beat and its flutter can sometimes be seen on an early ultrasound. Facial features are starting to form, and small buds are appearing that will become the arms and legs. The brain and nervous system are also growing at a remarkable pace.
Your body this week
Nausea may become stronger this week and can strike at any time of day, not only in the morning. It is also common to feel very tired, notice tender breasts, and experience mood swings. Try to be gentle with yourself, because your body is working incredibly hard.
Tips for this week
To ease nausea, try eating a plain cracker before getting up and having small meals throughout the day. Avoid strong smells that bother you and allow yourself plenty of rest. If nausea is stopping you from eating or drinking, speak with your doctor.
