Pregnancy Week 12

At week 12 of pregnancy the baby is around 2 1/2 inches long and about an ounce in weight. Although the movement of the baby wont be felt until a little further along, the baby is developing, growing, and moving around rapidly. At this point in the pregnancy, the brain will be developing and releasing hormones while the genitals begin distinguishing weather the baby is male or female.

By the end of this week, the uterus will bulge out above the pubic bone and continue to grow rapidly enough to support the growing baby inside. Many women report skin changes that occur during this week. Freckles tend to darken, a vertical line down the abdomen, referred to as the linea nigra, may form, the areolas will darken, patches of brown skin on the face and neck may appear. Discontinue use of any creams that may have a large dose of vitamin A because it could harm the liver and jaundice of the baby. The increase of progesterone during pregnancy causes the valve between the stomach and esophagus to loosen up, therefore heartburn is often a complaint. Some suggested way to help with the heartburn include eating less at each meal and having more meals thorough the day, drinking liquids prior to or after the meal instead of during, watching the junk food intake, and not eating before going to bed.

Some safety concerns during the period where the stomach begins to bulge includes the use of a seatbelt at all times. Seatbelts are life savers which are very important during pregnancy. Although most often when the uterus appears to be larger than normal the cause is from miscalculation, by twelve weeks the physician can perform an ultrasound to determine whether the cause is twins. Multiple pregnancies involve a higher level of risk but the risks reduce after week 12. For example, it is possible that both twins do not make it to term, but, if one twin is lost before week 12, it will reabsorb back into the body to prevent any damage to the other twin or to the mother.
