Your baby's development
Your baby is now the size of a green olive, about 2.5 cm
This week the tail has disappeared completely. The nape, eyelids, mouth and the tips of the fingers and toes are clearer. Your baby looks like a tiny person. Organs such as the brain, heart, lungs and stomach have begun to form and keep developing. Muscle cells have also begun to form, and your little one will make their first movements. But these movements are so small that you can't feel them yet.
Your body
At this stage you can feel outward changes in your body, as your tummy and breasts are both bigger. Your emotions may be hot-tempered and changeable. Don't be surprised; this is common in pregnancy because of the changing hormones in your body.
Morning sickness symptoms will still leave you quite tired. Coping with nausea and vomiting in pregnancy isn't easy, is it? But it also shows that your baby is growing every day. Nurturing a tiny life is hard work. Your body is working overtime to prepare for motherhood because of the development of the placenta - your baby's lifeline. What's more, your body's metabolism and hormone levels have risen significantly, which causes a drop in blood sugar and low blood pressure. This will ease quickly in a few more weeks, hang in there!
Advice for you
If main meals are too hard, eat at least six small but nutritious meals throughout the day. Not only are small meals easier on your stomach, they also keep your tummy a little bit full. Right now, focus on the foods you find least upsetting. Ginger foods such as preserved ginger, ginger soup and ginger sweets...are also effective at easing morning sickness.
