OK, Becky, I just sent this to a friend and thought I'd copy it here, even though I know you don't need it. Did you get a copy of
A Child Is Born yet? BEST book on pregnancy around, if you ask me (which you didn't.) The library will have a copy.
THE WITTLE BITTY BABY:
4 weeks: From the embryonic disk (ecto-, endo-, and mesoderm) the body segments that will become the spine, brain and spinal cord appear. Heart, blood circulation, and digestive tract take shape. Embyo less than 1/4".
8 weeks: Rapid development. Heart starts pumping blood, arms & legs (and fingers and toes!) developed. Facial features are discernible, as are divisions of brain. Ears develop from skin folds; tiny bones and muscles are formed beneath the thin skin.
12 weeks: Heartbeat discernible by ultrasound. Baby has more "human" shape as lower body develops. Sex of child can be determined. Kidneys start making urine. Movement begins!
16 weeks: Muslces have matured and nervous system exerts control. Blood vessels rapidly develop. Hands can grasp and legs can kick. All organs begin to mature and grwo. Fetus is about 1/2 pound. Pancreas makes insulin.
20 weeks: Vernix protects body, fine hair covers and eeps oil on the skin. Eyebrows, eyelashes, and head hair develop. Fetus develops regular schedule of sleeping, sucking, and kicking.
24 weeks: Skeleton develops rapidly as bone-forming cells increase activity. Respiratory movements begin. Weight - about one pound, ten ounces.
28 weeks: Fetus can breathe, swallow, regulate temperature. Surfactant forms in lungs. Eyes start opening and closing

. Baby is now 2/3 of the size it'll be when born.
32 weeks: Brown fat deposits developing beneath the skin to insulate baby following birth. baby has grown to about 15-17" and begins storing iron, calcium, and phosphorus.
38 weeks: The entire uterus is occupied by the baby, thus restricting its activity. maternal antibodies are transferred to baby, and last about 6 months until the baby's immune system takes over.
YOU:
4 weeks: Miss your period, breasts may get tender or bigger. Fatigue, urinary frequency may begin, persisting for 3 or more months.
8 weeks: Morning sickness, may persist to 12 weeks. No noticeable weight gain.
12 weeks: Braxton Hicks contractions can begin this early and are possible throughout pregnancy. Potential for urinary tract infections lasts throughout pregnancy. Placenta is producing hormones!
16: Weight gain of about a pound per week (little less.) More energy than before. More "down-there" secretions (the DIS edits the word ******l

) - worry only if they are stinky, itchy, or really irritating. May need to begin wearing maternity clothes.

Pressure on bladder lessens and urinary frequency decreases.
20 weeks: Breasts start secreting colostrum, nipples get darker. Can feel faint or dizzy, especially when standing up. Vericose veins may show up. Nasal stuffiness, beginning leg cramps and constipation, too, but...You feel the baby moving!!!
24 weeks: Backache and leg cramps. Skin changes on tummy. Acne. Possible redness on palms of hands and soles of feet. Nosebleeds possible. Some women's abdomen's itch as the skin stretches. If it happens, it'll probably last till the baby is born.
28 weeks: Hemorrhoids! Heartburn! You start breathing differently - with your chest instead of your abdomen (most people don't notice). Some women get "sick of being pregnant" and just want the baby to show up. Good time to take childbirth classes!
32 weeks: Breasts full and tender. Urinary frequency comes back big-time! Swollen ankles. Problems sleeping. Some women, especially overweight ones, have a little shortness of breath here and there, and should take it easy when they do.
38 weeks: Some women get a "burst" of energy, others get really tired. Backaches and leg cramps get worse. Braxton-Hicks contractions intensify.
