6 Weeks Pregnant: What's Going On

Pregnancy week 6

Your little one's heart tube, which formed last week, continues its development. It will gradually grow into four chambers and start to beat like a tiny drum. Find out more about pregnancy week 6.

Your Baby at 6 Weeks Pregnant

Closed for business. An important milestone occurs this week: The neural tube starts to close over what will become your baby's spinal cord. 

Face forward. This week, tiny folds of tissue are developing at the top: These will eventually become your little one's chin, cheeks, and jaw. The areas that will be the eyes and nose have started to project as bumps, and the inner-ear structure is pushing inward. 

Picking up the beat. The heart tube is gradually growing into four primitive chambers and starts to beat like a tiny drum. Other major organs like the kidneys and liver are also beginning to take shape. The lungs each exist as a single tube, and they're starting to form into pouch-like structures; they've got lots of blossoming to do before they're ready for air. 

Measuring up. Your little one keeps growing bigger, now measuring about 0.1 inch, or 2.5 millimeters.

Your Pregnancy at 6 Weeks

Conditions with a cause. Your breasts may be tingling or tender because of increased blood flow; this is just your body getting them ready for breastfeeding. Be sure to wear a supportive bra, even at night if it helps. You may also be experiencing constipation because of an increase in progesterone, which slows down the digestive tract. To deal with this problem, exercise regularly and eat a balanced diet, including lots of high-fiber foods. Shoot for at least eight glasses of water a day. 

Losing your lunch? About 70 percent of pregnant women experience some morning sickness, with the first trimester being the worst. Nausea is triggered by hCG, the pregnancy hormone that's secreted right after implantation. Though you can't prevent morning sickness, there are measures you can take to help relieve the symptoms.
