The tiny remains of a tail will now be disappearing. Your baby is now called a foetus (sometimes spelled fetus). Facial features such as the nose and mouth are developing, but the eyelids will be closed until around 27 weeks. The baby is starting to move in response to external light and sounds.
When to start telling family, friends and colleagues about your baby can be a dilemma. By now you may have known you're pregnant for over a month. Traditionally many couples wait until the end of the first trimester, because the first 12 weeks of pregnancy are the most likely time for losing your baby through miscarriage. You don't have to tell your boss about your pregnancy at 9 weeks. You can start to find out about maternity leave from work though.
Eating for two can seem like a great excuse to gobble all your favourite foods during pregnancy. In fact you don't need to eat very many more calories. It's only in the last few months that you will need to increase your calorie intake, and even then it should only increase by about 200-300 calories a day. At this stage, just make sure you're still eating a balanced diet - instead of high fat snacks like cakes and crisps, try a handful of dried fruit or some carrot sticks. Your midwife will monitor your weight.
