Week 7

Found this online, it tells what is happening with the baby:

Baby is almost half an inch long now!

The brain is starting to develop, the teeth and the inside of his mouth are forming, and his ears continue to develop. The eyes already are starting to develop colour.
The veins are clearly visible due to the paper thin skin.

You can't feel the movements yet, but your baby is quite hyperactive.
You may still feel quite nauseous (and not only in the morning) - tell me about it!. The nausea should fade as your pregnancy continues, though you may continue to make frequent trips to the bathroom.
