Pregnancy Week 6

Week 6 is marked by rapid growth. The neural tube along your baby's back begins to close.

Your baby's heart will begin pumping blood which may even be detected at an ultrasound examination.

Small buds that will eventually become arms and legs will develop.

The beginnings of facial features will appear, including passageways that will make up the inner ear, optic vesicles which will later form the eyes and arches that will contribute to the jaw.

By the end of this week, your baby will be about 3/16 to 4/16 inches or 4 to 6 millimeters in length from crown to rump.

You may have noticed a change in your waistline already.

Nausea can become more pronounced during this week.

You may have increased sensitivity to food smells.

To help alleviate your nausea, drink plenty of fluids and avoid having your stomach completely full or empty.

Remember to get plenty of rest, especially if you are feeling another common first trimester symptom, fatigue.
