Your baby weighs about 1/8 of an ounce — just bigger than a penny. The tadpole-like tail is almost gone, and in its place are two little legs. Your baby's head is still huge compared to the body, but it will get more proportional in the weeks to come. Inside, the reproductive organs are forming — although it's still too early to tell on an ultrasound whether you're having a boy or girl. If you look closely, though, you might see your baby move!

Hopefully you're over any morning sickness you had. Now, you should be putting on weight. It won't be long before friends and co-workers start to notice your baby bump! Your baby is growing quickly now and is getting more proportional – now the head makes up only 1/3 of your baby's body. Helping your baby grow is the placenta, which is serving up a steady supply of nutrients and disposing of wastes. If you're having a girl, her ovaries are already filled with hundreds of thousands of eggs.
