Your baby at 7 weeks
Your baby is the size of a small blueberry. Your little one is 4- to 8-millimetres (0.15 to 0.3 inch) long this week, a little larger than the width of your little-finger nail.
Although brain development will continue long after birth, the basic sections have formed. As the week progresses, this organ will divide into three parts: fore-brain, mid-brain and hind-brain. The fore-brain will be responsible for things like reasoning, problem solving and forming and retaining memories. The mid-brain will relay electrical signals to their final destinations in the brain. The hind-brain will take care of breathing, heart rate and muscle movement. Limbs are also growing fast: arm and leg buds have sprouted.
Your pregnancy at 7 weeks
The pee parade
Raging hormones and increased blood volume cause your body to produce more fluid, so you may find yourself heading to the ladies’ room more often than before. However, it’s important to stay hydrated – you should continue to drink extra water throughout your pregnancy.
Make sure to order your meat well done and avoid kitty-litter duty throughout your pregnancy. Toxoplasmosis, an infection passed along through raw meat and cat faeces, can be harmful to your baby (but not to you). In fact, you may have already had it without knowing it – if so, you are immune.
Did you know?
The areas of the baby’s brain are beginning to form and the buds that will become arms and legs are sprouting. The ears and tip of the nose can now be seen.
