Your baby is about the size of a prune 3.3cm (head to bottom) and weighs around 4g...
Your baby has almost doubled in size in the past three weeks and bones and cartilage are starting to form. The arms, which now have elbows, can flex.
The jawbones are developing and already contain all the future milk teeth.
Your baby's heart is now completely formed and beats at approximately 160 beats each minute. Your baby's stomach is already producing digestive juices and the kidneys are producing urine. If your baby is a boy, he is already producing testosterone.
If you haven't noticed them before you may now see a network of blue veins crisscrossing your heavier, achy breasts and expanding waistline. These veins carry the extra blood that is circulating around your body. During pregnancy, your blood volume increases so the veins have to get bigger to cope with the additional blood supply.
Constipation is another common pregnancy symptom that you may be experiencing. The best way to combat it is to eat plenty of fibre-rich foods such as whole grains, fresh fruit, dried fruit, raw or lightly cooked vegetables and nuts and seeds. Drinking plenty of fluids will also help. Don't be tempted to use over-the-counter laxatives without consulting your doctor or chemist first.
You may have noticed an increase in clear or white vaginal discharge, which is quite normal. However, a discharge which is coloured, smelly or causes itching or soreness could be a sign of a vaginal infection so you should seek advice from your doctor.
At 10 weeks pregnant you may also be getting a few spots - blame your hormones again!
