April 27th 2017 - 9 Weeks - Baby is the size of a Green Olive! During your 9th week of pregnancy, your baby is busy growing. Its face looks more baby-like each day - its eyes are developed but concealed, and its nose, lips, and ears are becoming more defined. It's also starting to exercise its expanding muscles. Its fingers an toes are looking less like stubs. Although its a wiggler - and you could see that on an ultrasound - it's still so small that you won't feel these movements. Its reproductive organs are developing, but even if you sneaked a peek you wouldn't be able to tell that its a she or he (and neither could your doctor at this point).

April 20th 2017 - 8 Weeks - Baby is the size of a Raspberry! No wonder you're excited to tell someone about your pregnancy. Your baby is no longer a mass of cells, but he's looking more and more like a miniature baby-to-be. During your 8th week of pregnancy, your baby's face is becoming more defined: eyelids have formed, its nose is beginning to protrude, and its upper lip is taking shape. Where there once were only stubs, fingers and toes are starting to develop from its arms and legs. Its heart is beating quickly and strong inside its tiny body.

April 13th 2017 - 7 Weeks - Baby is the size of a Blueberry! This is another big week for your wee one. Early in week 7, the embryo still looks like a tadpole, but by the end of the week it will have transformed into a tiny being that's distinctly human-like. Its body is continuing to lengthen, the arms begin to bend at the elbows and curve around the heart, which is beating even more rhythmically now. By the end of this week the embryo's whole skeleton - made of bendable cartilage, like a shark - will be fully formed. (To be replaced by bone soon enough). The baby has a digestive system now, as well as kidneys, liver, heart, spleen, and even an appendix. Your placenta has sprouted hundreds of minute hair-like projections (called villi), making it look like a fuzzy ball. The villi have the important job of carrying nutrients and oxygen from your bloodstream to your growing baby.

April 06th 2017 - 6 Weeks - Baby is the size of a Sweet Pea! Your embryo is growing at lightning speed, adding 1 millimeter to it's tiny self each day. If that doesn't sound like a lot, imagine that you grew by one-third overnight and you'll appreciate how hard the little tyke is working! By the end of the week the embryo's head will be bigger than its body. It has little limb buds that are starting to lengthen into shoulders, arms, hands, and even the beginnings of fingers; and little leg buds that, by the end of this week, will lengthen into thigh, leg, and foot parts. That heartbeat that started last week has become more rhythmic and regular, and the heart has divided into two (of four) chambers so far. But this week's biggest news is that the embryo is growing an umbilical cord, its lifeline to nutrients and oxygen and its constant companion for the next 34 or so weeks!

March 30th 2017 - 5 Weeks - Baby is the size of an Apple Seed! In week 5, baby's still just an embryo, but it's growing more furiously and changing rapidly than it will at any other time in it's life! Your baby's forming a "C" shape, sort of like elbow macaroni. The tiny tube-shaped being already has a head, back, front, and... tail. (Don't worry, the tail gets absorbed into the body). At the beginning of this week, the embryo already has 125,000 cells - enough to fill every seat in two NFL football stadiums. Even more amazingly, the baby's tiny heart has already formed, and will have started to beat (though these heart contractions won't become regular for a few more weeks). The baby's spinal cord and brain are beginning to form, as are key organs - including the lungs, liver, and pancreas - and the placenta, which will supply your baby with oxygen and nourishment.

March 23rd 2017 - 4 Weeks - Baby is the size of a Poppyseed! Some women swear they feel the fertilized egg hunker into the lining of the uterus and get cozy. (The official term: implantation. The feeling: A twinge similar to ovulating). The rest of us won't have any notion we're pregnant for at least another week. While we're oblivious, baby's getting busy. During week 4 the blastocyst burrows into the womb and separates into cells that will become the placenta and cells that will become the baby. The Great Divide isn't all that happens this week. The layers of the embryo itself actually start to differentiate into specialized parts. The outer layer will become baby's hair, skin, eyes, and nervous system; the middle layer will soon be the heart, reproductive organs, bones, muscles, and kidneys; and the inner layer becomes the baby's liver, lungs, and digestive system.
