By week 9, your baby is about the size of a grape, measuring about 1 1⁄2 inches, and weighs a fraction of an ounce.

The tiny remains of a tail will now be disappearing. Your baby is now called a fetus. Facial features such as the nose and mouth are developing, but the eyelids will be closed until around 27 weeks. While your baby is still extremely small, he/she is now ready for rapid weight gain. The baby is beginning to look more like a little person. The eyelids are fully formed, have fused shut, and will open again during week 28. All the baby's joints such as the knees, elbows, shoulders, ankles, and wrists are working and allowing the baby to move about freely within the amniotic sac. Your baby's heart began beating around day 24, but now his/her heart has divided into four chambers, and the valves are beginning to develop. Your baby can also make a fist, and he/she may begin sucking his/her thumb.

The baby is starting to move in response to external light and sounds. By now you may have known you’re pregnant for over a month. Traditionally many couples wait until the end of the first trimester to start telling family, friends about your baby, because the first 12 weeks of pregnancy are the most likely time for losing your baby through miscarriage.

Eating for two can seem like a great excuse to eat all your favorite 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. 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.

You still may not physically appear pregnant to other people, but you definitely are beginning to notice several changes. It may be that you are experiencing mood swings, and/or you may notice an increase in heartburn and feeling more bloated. You can avoid heartburn by eating smaller meals throughout the day instead of eating three larger meals at typical mealtimes. You can also prevent heartburn by avoiding lying down after meals and avoiding spicy or greasy foods.

At this point in your pregnancy you may begin to feel more fatigued. This may be caused by the hormonal changes or trouble sleeping at nigh .Not sleeping well at night may be caused from not being able to find a comfortable position or from frequent trips to the bathroom. If you are having difficulty resting, try changing your sleeping positions.
