Pregnancy week by week email update

You'll ovulate, and if egg meets sperm, you'll be on your way to pregnancy! Your baby is a tiny ball — called a blastocyst — made up of several hundred cells that are multiplying quickly. Deep in your uterus, your baby is an embryo made up of two layers, and your primitive placenta is developing. Your tiny embryo is growing like crazy, and you may be noticing pregnancy discomforts like sore breasts and fatigue.

Your baby's nose, mouth, and ears are beginning to take shape. You may be having morning sickness and spotting. Your baby — still an embryo with a small tail — is forming hands and feet. Your uterus has doubled in size. Your baby is constantly moving, though you can't feel it. Meanwhile, you may be making decisions about prenatal tests. Nearly an inch long now, your baby is starting to look more human. You've probably noticed your waist thickening. Your baby has finished the most critical part of development!

Organs and structures are in place and ready to grow. Your baby's hands will soon open and close into fists, and tiny tooth buds are appearing underneath the gums. Your little one's teeny toes can curl, her brain is growing furiously, and her kidneys are starting to excrete urine. It's the last week of the first trimester! Your baby now has exquisite fingerprints and is almost 3 inches long.

Your baby's tiny features are making different expressions. And you may be feeling more energetic and less nauseated. Your baby can sense light and is forming taste buds. Have a stuffy nose? It's a surprising pregnancy side effect. Get ready for a growth spurt. In the next few weeks, your baby will double his weight and add inches to his length.

Your baby's skeleton is changing from soft cartilage to bone, and the umbilical cord is growing stronger and thicker.

Your baby's genitals are developed enough to see on an ultrasound. An increase in appetite is normal now. Go ahead and sing: Your baby may be able to hear you!

And if your sides are aching, it could be round ligament pain. Congratulations, you're at the halfway mark in your pregnancy! Your baby is swallowing more now and producing meconium. Feeling your baby move? Those early flutters will turn into full-fledged kicks.
