Week 1 to 2

It might be a little confusing, but in the first two weeks of ‘pregnancy’, the pregnancy hasn't actually started.

Week one is the first day of a woman's menstrual period.

At the end of the second week, and an egg is released. It is at this time that conception is most likely.

Beware of a tricky propaganda stunt that happens here!

Pregnancies are measured two ways: By gestational age and by embryonic (or fertilization) age.

Gestational age is measured from the first day of the last menstrual period. Embryonic age is the actual age of the preborn child, measured from the moment of conception. Because conception is usually about two weeks into a woman's cycle, the embryonic age is usually about two weeks behind the gestational age. Is that making sense so far? Good. Because here's the logical game pro abortion advocates will play.

They'll say there's absolutely no baby in the first two weeks at all! And technically, if they were talking about the first two weeks by gestational age, they'd be right. But when they're talking about abortion an embryonic human, they're actually talking about gestational week three, or embryonic week one. And, in fact, by that time, the preborn child is not just a random assortment of cells: He or she is already a whole living human organism with a full set of unique DNA and performing all the necessary functions of life. In fact, by week three gestational age, or week one embryonic age, the central nervous system and heart are already developing!

Week 3

Week three is when fertilization occurs. When the sperm enters the egg, a zygote containing all of Baby's genetic information is conceived. Half of the her DNA comes from each parent. During the next few days after fertilization, the preborn child's cells rapidly divide and multiply to form a blastocyst. A blastocyst is made up of inner cells, which will soon specialize to form the embryo, and outer cells, which will become the membranes that nourish and protect the Baby in her embryonic stage. .

Week 4

Once Baby's blastocyst reaches the uterus, it buries itself in the wall of the uterus. By now, the uterus lining is thick with blood to support the baby.

Week 5

This is the official start of the embryonic period, where all the major systems and structures will develop. Differentiation starts now, where the Baby's cells continue to rapidly multiply and take on specific functions (differentiation). Blood cells, kidney cells, and nerve cells all begin to develop. Baby rapidly grows, and visible external features begin to form. Her brain, spinal cord, and heart begin to develop, as well as her gastrointestinal tract. At this point, Baby is most vulnerable to things that may cause birth defects, such as certain medicines, drugs, alcohol, infections (ie. rubella), and other factors.

Week 6 to 7

Baby's arm and leg buds start to grow, and her brain forms into five specific areas. Some cranial nerves are visible, and her eyes and ears begin to form. Tissues start to develop, which will become Baby's spinal cord and other bones. Her heart is continuing to grow, and now beats with a regular rhythm, which can be observed using a vaginas ultrasound. By now, blood is pumping through her main vessels.

Week 8

Baby's arms and legs have grown longer, and little hands and feet that look like tiny little paddles have begun to form. His/her lungs have also started to grow.

Week 9

At this point, nipped and hair follicles form and Baby's arms grow elbows. You can now see Baby's toes, and all of her essential organs have begun to grow.

Week 10

Baby's eyelids have developed more and now they can close. Her outer ears are taking shape, and her facial features are getting more distinct. Her intestines rotate, and at the end of week 10, Baby's is officially an embryo! Moreover, her heart tones might now ve detectable by Doppler testing.

Week 11-14

Baby's face is now well formed, and her eyelids close. They won't reopen until about week 28. Her limbs have grown longer and thin, and now she has nails on her fingers and toes. Her liver is producing red blood cells. This is also the time when a preborn child's genitalia develop. Baby's head is very big—almost half her body size! She can now make a little fist with her little hands, and the first tooth buds of her baby teeth emerge.

Week 15-18

Baby's skin is almost transparent, and a very fine layer of hair, called lanugo, develops, and Baby's bones are starting to get harder. She can now move around and stretch, and she can make sucking motions. 😊

Weeks 19-21

Be careful what you say! Baby can hear you now. She is more active, and you might feel a fluttering in your lower abdomen. This is ‘the quickening’, when you can feel Baby's first movements. Baby can swallow now, practicing for when she's out in the world with us.

Week 22

Lanugo hair covers Baby's whole body now. Her eyebrows and lashes develop, and with increased muscle development, she will be moving more. Now, Baby's heartbeat can actually be heard with a stethoscope!

Week 23-25

Baby's bones marrow will begin to produce blood cells, and the lower lung airways develop.

Week 26

Now, Baby's whole eyes are developed, including her eyebrows and eye lashes. She may even startle if she hears a lous noise. Her unique footprints and fingerprints are forming now. She has air sacs forming in her lungs—but they're not ready for the outside world quite yet!

Week 27-30

Baby's brain is growing rapidly, and her nervous system is developed enough now to control some body functions. Her eyes can now open and close. Her respiratory system is still immature, but it is producing surfactant, which helps the air sacs fill with air.

Week 31-34

Baby is growing really fast, and gaining lots of fat—all to help prepare for her arrival to the outside world. She can breath rhythmically, but her lungs still aren't fully developed yet. Her bones are fully developed, but still very soft. Baby will begin to store iron, calcium, and phosphorus.

Week 35-37

Baby is about as long as she's going to get, and her skin is less wrinkled now, since there's more fat under it. She has defined sleeping patterns, and her heart, blood vessels, muscles and bones are all filled developed!

Week 38-40

The lanugo is all gone, except for on her upper arms and shoulders. The lanugo on her head has been replaced with thicker, coarser hair. At this stage, both male and female preborn children will have small breats buds. Get ready! Baby will be meeting you very soon!
