Well .. I'm 27 weeks. That officially puts me in the third trimester. Only 3 more months to go. I need to invest in some bigger shoes - my feet and ankles are extremely swollen. Yay for summer time. I think I'm going to go soak my feet in ice water...
Week 27:
Welcome to the third trimester. The home stretch! Around this time you will begin to really put on the weight, this will last until about week thirty-six. Although some cultures dictate otherwise, weight gained during pregnancy is not fat or unhealthy, but rather, necessary for a healthy pregnancy and baby. The weight that you gain will be distributed in several places. In the beginning of pregnancy you may have noticed that your breasts got larger. The average breast before pregnancy weighs about 7 ounces and during pregnancy each breast can weigh up to an average of 28 ounces! Some of the weight will go to body fluids (amniotic fluid, blood volume, etc.). Remember that your blood volume increase by 30-50% during pregnancy. And let's not forget the baby and the placenta! Add this to a few measly pounds put on as maternal fat stores, and you average about 25-30 pounds. The most important thing to remember is that a healthy diet is more important than what you gain. Some women will gain more, as in the case of women who were underweight to begin with, and those carrying multiple babies. While others will gain less. Pregnancy is not the time to go on a reducing diet. Even if you are overweight, reducing can actually harm the baby by burning your maternal fat stores sometimes toxins can be released that are harmful to the baby.
During this week, the brain continues its rapid growth, and the lungs continue to grow. Eyelids begin to open, and the retinas begin to form. The baby will grow over 1/2 inch this week and will be about 1 1/3 feet long (from crown of head to the toes or 9.6 inches from crown to rump)!
Your baby's skin is very wrinkled from floating in water. This will stay this way until a few weeks after birth as your newborn fills out into a baby. Although take heart in the fact that your baby's looks are assuming the looks that they will have at birth! Baby has also hit the 2 pound mark (900 grams).
Some pictures...
Your baby is almost completely formed, and is beginning to deposit brown fat on his or her body. The purpose of the brown fat is to retain body heat. Newborns are notoriously bad at regulating body temperature at first. This is particularly a problem for a baby born early. Babies born at this point have some chances of survival with very special care. They will be in the Intensive Care Unit, probably for many weeks. Usually we say that you can expect them to stay in the NICU until their due date. A major problem with premature babies is lung development. If preterm labor is detected early enough a steroid shot, called Betamethasone, can sometimes be given to enhance lung development. She weighs in at 1 lb 5 ounces (595 grams) and 30 cms or 11.8 inches total length!
Week 22:
The baby is getting bigger and continues to practice for life outside the uterus. This week your baby has fully developed eyelashes and eyebrows and the hair on your baby's head is continuing to grow as his brain begins a rapid growth process. The fetus has fully formed fingerprints and loud noise can wake up the baby. He may begin kicking and turning around, too. Your baby's heartbeat can be heard with a stethoscope. His nose is taking on a more defined shape as cartilage (the soft bone) appears. If you baby is a boy, the testes have begun to descend from the pelvis into the scrotum. Your baby is approximately 30-32 cm (10.8 inches) and weighs about one pound.
This is an impressive week for growth! Your baby weighs approximately 250 grams (8-9 ounces) and is about 22 cm or 6 inches long.
If you are having a girl, her ovaries now contain primitive egg cells. Lanugo (a covering of fine soft hair) appears all over the baby's body. This fine hair will remain until birth draws nearer. Sometimes you can still see some on the baby's face and ears after birth. Also apparent is vernix, a milky white covering that protects your baby's skin from its aquatic environment. Can you imagine how wrinkled you'd get if you were in water for nine months? The placenta continues to grow and offer nourishment for your baby while the permanent teeth buds are forming behind the already formed milk teeth buds. Growth becomes rapid now and your baby begins to store iron for the production of red blood cells. Your baby can even dream (REM sleep)!
And we couldn't be happier. Madisyn Elizabeth will be her name. :) The doctor was concerned about my low-lying placenta, which is covering my cervix. They will re-check this around 28 weeks to check on the position of the placenta. If it doesn't move by the time I am 36 weeks, they will have to schedule a c-section at that time.
Week 18::
Your baby is growing rapidly. His bones are continuing to harden and the pads of his fingers and toes are formed. He even has his own set of fingerprints developing as well. Your baby is approximately 5.5 inches and weighs about 200 grams (7.5 ounces). Your baby can kick, swallow, and sleep. He also is developing his stomach, intestine and colon and the intestines collect meconium (the initial stool a baby will pass after birth). If the baby is a boy, the prostate will begin to develop this week as well. The skin is still a bit pink and transparent and his ears still stick out from his head. The four-chambered heart begins to build up muscle cells and is pumping between 25 and 30 quarts of blood per day.
Week 13:
There is a lot going on with your baby this week. Your baby's intestines are migrating from the umbilical cord into his or her abdomen. The villi are also forming in the intestines, and these help in peristaltic movements and digestion. The liver begins to secrete bile and the pancreas is even secreting insulin! All twenty teeth have formed and are waiting under the gums, while your baby has begun to practice swallowing by taking in the surrounding amniotic fluid and pass it back in his urine. Your baby can smile and his vocal cords are quickly developing, too. He looks more and more human as his eyes move closer together and the ears are beginning to move to what will be their normal positions. Your baby weighs between approximately 13 and 20 grams (1/2 and 3/4 ounce) and is approximately 2.5 to 3 inches long. The placenta and baby are about the same weight now.
This week marks the end of the embryonic period. Most of the vital systems are developed now, and baby starts really growing, at times, growing as much as an inch this week.
By now, nearly all of your baby's organs, structures and systems are fully formed. The heart begins pumping several quarts of blood through your baby's body every day. Your baby has also begun to develop nerves and a spinal cord, allowing him to feel some types of pain. While your baby's brain is not the same size it will be at birth, it does have the same structure. Fingers and toes have separated and hair and nails continue to grow. Your baby is approximately 2.5 - 3.5 inches and weighs about 12 - 14 grams. Also, the external genitals can now show definite signs of male and female gender. Before, Where there was only reflex movement, your baby now moves spontaneously and at random, although his movements are still too slight to be felt. With the use of a Doppler, you may be able to hear your baby's heart beat at this office visit. It will sound very fast, similar to the sound of a running horse's hooves. Once you hear this sound, you can rest assured that your risk of miscarriage is greatly reduced.
