During pregnancy week twelve the baby moves around quite a bit though the movement may not be felt much by the mother. The baby will weigh around half an ounce and be about 2.5inches in length. During this period of pregnancy the brain of the fetus will be undergoing more development and hormones will be released. The genitals are also more distinguished to show whether it is a female or male baby.

Now the uterus at 12 weeks pregnancy will begin to bulge out over the pubic bone and grow fast to accommodate and support the growth of the baby inside it. Some women experience changes in the skin during this period, the freckles darken, there is a vertical line formed on the abdomen, there are brownish patches on the neck and face and the areolas become darker. If you have been using any creams which contain large amounts of vitamin A then this should be discontinued as it is harmful to the baby and can cause liver problems and jaundice in it.

The mother will have to take care of her pregnancy diet during this stage of her pregnancy as she will have heart burn which is brought on by the loosening up of the valve between the esophagus and the stomach because of the progesterone increase due to the pregnancy. Sometimes if the pregnancy diet is made up of more frequent smaller meals instead of large meals this could help and also drink water before or after a meal instead of doing this in between the meal. Try and control eating junk foods and also avoid going to bed immediately after dinner.

Now the mother has to ensure the safety of her baby and herself and it is a must to use a seat belt when traveling. Sometimes the uterus might seem to be larger than it should during this period, and it could be a miscalculation or twins. An ultrasound will be able to tell you whether you are expecting twins.
