Your baby now has three layers (outer, middle and inner), and each layer will develop into different parts of the body. |
|
|
| • |
It also becomes more pear-shaped, with the head region broader than the tail end. |
|
|
| • |
A neural groove also develops along the axis, and is the precursor of the nervous system. |
|
|
| • |
The heart and primitive circulatory system is also rapidly forming. |
|
|
| • |
Cell differentiation accelerates as it develops more bumps and ridges, including a head fold on either side of the primitive streak. |

You're probably noticing that your period is late. |

If you haven't already, you may begin to have pregnancy symptoms. Your breasts will become swollen and tender as milk glands multiply; you may need to use the bathroom more frequently as the growing uterus presses on your bladder; you may feel nauseated from "morning sickness" and experience headaches caused by rising hormones; you may feel hungry more often as your body now requires energy for two people. |

| • |
The infamous "morning sickness" affects about 70% of all pregnant women, and doesn't only occur in the morning. Good thing is, it usually goes away by Week 13. |
