During week 14 of pregnancy, you should be experiencing less nausea and less frequent urination. Your energy levels should be increasing. You may begin experiencing constipation due to hormones. If it becomes a problem, add more fiber to your diet and make sure you are drinking plenty of fluids. You may develop cravings or food aversions, loving foods you previously hated or vice versa. The changes in your hormones are partly responsible for this.
You may have developed a dark line down the middle of your abdomen to your pubic bone called a linea negra. Your uterus is now the size of a grapefruit. The areolas (the darker colored part around your nipple) of your breasts are darkening and growing larger in diameter. Your body is preparing for breastfeeding by growing new milk ducts. Your nipples may also be more sensitive.
When you are 14 weeks pregnant, your baby is about 3 to 4 inches long. He or she weighs about 1 ounce. All of the baby's nourishment is being received from the placenta. The placenta has also taken over all hormone production from the ovaries. These hormones will continue to play a vital role in maintaining your pregnancy along with the changes in your body.
The baby is now about 12.5 cms or 4.92 inches. Your baby is now producing urine and actually urinating into the amniotic fluid. It also can practice "breathing" the amniotic fluid in and out of its lungs.
Your baby will start to get covered with a soft, fine hair over its body called lanugo. The lanugo will be shed before he or she is born and replaced with thicker, coarser hair. Your baby's sex organs have fully differentiated into male or female.
Other fetal development that occur around week 14 of pregnancy include the ears having moved from the neck onto the head, complete digestive glands, the thyroid starts to produce hormones, and the vocal chords are complete. Your baby will begin to inhaling and exhaling.
