Dive in, and congratulations! After fertilization and implantation, a baby is at first just an embryo : two layers of cells from which all the organs and body parts will develop. Growing quickly, your baby is soon about the size of a kidney bean and constantly moving. The heart is beating quickly and the intestines are forming.

Your budding son or daughter's earlobes, eyelids, mouth, and nose are also taking shape. Tiny, unique fingerprints are now in place, and the heart pumps 25 quarts of blood a day. As the weeks go by, your baby's skeleton starts to harden from rubbery cartilage to bone, and he or she develops the ability to hear. You're likely to feel kicks and flutters soon if you haven't already. They can blink their eyes , which now sport lashes.

And their wrinkled skin is starting to smooth out as they put on baby fat. They're also developing fingernails, toenails, and real hair or at least some peach fuzz , and adding billions of neurons to their brain.

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!
