Check out what happened with your little one's development last week.
The producers. Now that your fetus has completed the task of forming all the critical body structures, the organs go to work. The liver secretes bile, the pancreas produces insulin, and the kidneys form urine to carry waste away. The urine is excreted into the amniotic fluid. Your little one's intestines, which have partially resided in the umbilical cord, have moved back into the abdomen now that there's enough room to accommodate them. With muscle layers forming in the gut, it'll soon be time to get things moving through the digestive system, too.
Head long. Your little one is now about the size of a large plum, weighing less than 1 ounce and measuring anywhere from 2.6 to 4 inches. The head takes up half of that length, thanks to all that brain development. Over the next few months, the body will grow at breakneck speed to catch up. When your baby is born, the head will be only a quarter of his total length.
Welcome to the second trimester! Many women describe the next few months as the honeymoon period of pregnancy. The discomforts of the first trimester—fatigue, nausea, and frequent urination—ease up a bit, and you get a chance to really enjoy being pregnant. Many women even feel a surge of energy during this trimester. You've probably heard it described as the "glow of pregnancy." You'll start showing soon and maybe for the first time will truly start to feel pregnant.
Middle management. One reason why you may feel pregnant is that your waistline is starting to thicken. Your regular pants are probably getting a little snug, though it may be too early to move into maternity clothing, especially if this is your first pregnancy. But you might feel more comfortable in those cute maternity overalls you've had your eye on. Whatever you decide, dress with comfort in mind—go for loose-fitting pants, tops, and dresses.
From the experts. "A very few women develop a thyroid imbalance during pregnancy or in the first year following birth," notes Margaret Comerford Freda, Ed.D., R.N. "It's not a common occurrence, but the consequences are serious for the baby." Detecting an imbalance early is especially important for women with a family history of thyroid problems, rheumatoid arthritis, pernicious anemia, or very premature graying of the hair. Learn to spot the symptoms of both an underactive and an overactive thyroid.
