By the fifteenth week, even people who are around you will have started noticing the emerging baby bump. You should have gained a lot of weight, about 5-10 pounds over the past 14 weeks. However, you should not worry if not showing signs of a baby bump at this time because it is going to appear in a couple of weeks.
By the end of 15th week, the baby will approximately 4 inches long and weighing slightly more than 2.4 ounces. The growth in this week is rapid, and the baby’s senses are becoming very sharp.
Blood vessels: A dense network of blood vessels starts developing around this week and can be seen as a type of map with many lines from the heart. At this point, the skin is still not well developed and is approximately a paper thin so that most internal organs are visible.
Baby’s first hair/lanugo: On the thin layer of skin, a fine layer of hair called lanugo will develop except on nails, lips, feet, and toes. This hair will be shed off approximately the first eight months after birth.
Hands, legs, and bones: The baby’s bones continue getting harder starting from the joints while legs and hands elongate at a faster pace. The arms are long enough and can be stretched right in front of the face. The fingers and finger tips are also more distinct and grip firmer.
Baby passes time practicing: This is one of the most noticeable things at week fifteen. The baby intensifies practicing inhaling and exhaling the amniotic fluids. This is critical in helping the air sacs in the lungs to develop and get ready for actual breathing on delivery. By the close of the week, some babies are already sucking their thumbs which are very important in helping the tongue develop taste buds.
Intense kicks: Because the legs are developed, the baby will practice with harder kicks within the amniotic sac. However, many women are still not able to get the movements until the 20th week. However, if you listen carefully while relaxing in a quiet room, you can be sure of getting the moments.
As the baby belly bump continues growing at a slow pace, the doctor might consider taking the measurement of the uterus. The distance between the top of the pubic bone to the upper part of the uterus (fundal height) corresponds well with the number of weeks you have been pregnant. While it might not be necessary if the bump is still small, it is appropriate for mothers carrying twins.
Because of the fast expanding uterus, mothers are at a greater risk of suffering from urinary tract infections. It is estimated that approximately 5% of all pregnant women suffer from urinary tract infections at some point. If untreated, you are at a greater risk of suffering serious pregnancy complications.
