What happens in the 15th week of pregnancy?
During the 15th week of pregnancy, your baby measures about 4 -4 1/2 inches in length and weighs just over 2 ounces. Your baby's growth is pretty rapid and your baby's skin is very thin- as a result the blood vessels can be seen.
Lanugo- the fine hair covers your baby's body during this stage. The bones are getting harder and ossifying rapidly. Your baby now has taste buds and also may get the hiccups now and then.
CHANGES IN YOU
You might experience your ligaments stretching in your abdomen. As the uterus expands, the elastic tissue or the ligaments that support it stretch to house its growth. The process may cause twinges, cramps or at times pulling sensations on one or both sides of your lower abdomen.
At this point, some women start experiencing certain unexpected side effects well into their pregnancy. For instance, excessive salivation is fairly common during pregnancy. This should not be a cause of worry, though it can be a bit problematic at times.
A bloated abdomen is observed by 15 weeks. Many women gain anywhere from 5 to 10 pounds by now, and their uterus starts rising past their hipbones. Your doctor or healthcare provider will be able to feel your uterus about 3 inches or so below the belly button.
In the following weeks of your pregnancy, your healthcare provider will begin to take measurements of your uterus, which is referred to as the "fundal height". This measurement helps in confirming your due date, as it correlates with the number of weeks you are pregnant. The fundal height is defined as the distance between the top of your uterus and your pubic bone.
Your Baby's Development
Your baby is now measuring 4 inches in length and weighs more than 2.4 ounces!
Parents are often surprised by the softness of their newborn's skin. Your babyís skin is continuously developing, and itís so thin and translucent that you can actually see the blood vessels through it.
In the 15th week, your baby starts producing lanugo. This is nothing but the fine hair that covers your baby's body up until a few weeks before birth. Lanugo covers every part of your baby in uterus, except for the lips, penis, nails, palms, soles of the feet, and inner fingers and toes.
Characteristically babies will shed this hair by 8th month of pregnancy, but it may remain in some newborns for a short period of time. Pre-term babies are usually expected to be born with lanugo than full term babies.
Hair growth also continues on the eyebrows as well as the head. Your baby's ears are more or less in position now, though they are still placed a bit low on the head.
Your baby continues to grow rapidly as you continue your pregnancy week by week. If you peek inside your uterus during this pregnancy week 15 you would still be able to observe your baby's blood vessels through its paper-thin skin. Actually, the blood vessels that are forming in your baby's body make him or her appear pretty much like a map!
The bones in your baby's body also begin to get harder during pregnancy at 15 weeks and continue to do so throughout your pregnancy. Your baby, in the mean while, is spending most of his time practicing breathing, by inhaling and exhaling the amniotic fluid. The very act of doing so helps your baby's air sacs develop during pregnancy. Your baby continues forming taste buds at this particular point.
Internally, the baby's skeletal system continues to develop. The development if muscles also continues, and your baby is in all probability making lots of movements with his or her head, arms, wrists, hands, mouth, legs, and feet.
