Your BabyYour baby's organ systems are now functioning and he has a skeleton, nerves and blood circulation. Your baby's tiny feet are fully formed and shaped and could stand on an adult's fingernail. The most critical part of baby's development is now over, and the remainder of the pregnancy is about rapid growth, organ maturation and getting ready for delivery. In fact, your baby grows so quickly now that he will start out this week being approximately 21 - 25 mm or 0.85 - 1.0 inches and by the end of the week will be 44 - 51 mm or 1.75 - 2.0 inches and weigh approximately 7 grams! Your baby's head is about 1/2 of his body length. The baby's eyelids are fused now and the irises are developing. Your baby will begin to get baby teeth, fingernails, toenails and hair follicles this week, too.
Your BodyGuess what? Your uterus is about the size of a grapefruit already! While you probably haven't gained much weight so far, you may be a little concerned about weight gain during pregnancy. Most doctors say that you should gain approximately 1-2 lbs. a month in the first trimester, (a total of about 6 pounds). However, everyone is different and you may actually lose weight. That's normal and you'll be perfectly fine, particularly if you had a lot of morning sickness, nausea, or heartburn.
You might be getting your appetite back as your morning sickness subsides, but certain foods or smells may still make you nauseated. It is important to remember that good nutrition is important for both you and your baby. Take your prenatal vitamins, eat lots of fruits and vegetables, and get plenty of protein. Oh, and don't forget to rest.
