Your baby's development
Your baby is now the size of an orange. About 9 -10 cm long and weighing about 60 grams.
Pretty little hairs are starting to grow and eyebrows are appearing. Your baby's body is also covered with a layer of fine hair called lanugo to keep warm. This hair will fall out later. Your baby's intestines are also starting to make meconium.
Your body
You may feel mild pulling pains on both sides of your tummy. This is because the growing uterus stretches the ligaments (especially the round ligaments) thin, causing a dull ache or mild sharp pain in the lower tummy that gets worse when you change position (from sitting to standing or the other way round). To feel more comfortable, raise your feet or lie in a comfortable position to ease the pain.
By now you have also gained 1 - 2 kg, and your bump and breasts are bigger. So choose loose, comfortable clothes. Some mums-to-be may have more nasal and throat secretions; this is a physiological effect of oestrogen and progesterone.
Advice for you
Keep an eye on changes in your skin, do gentle exercise (swimming, walking or aerobics) and choose cool, airy clothes.

Fever in pregnancy
A temperature above 38°C counts as a fever. Please go to a health facility so a doctor can find the cause and advise on safe ways to bring it down; do not take medicine on your own.
