It's the time of implantation! Now it is no larger than a poppy seed (although a lot of sweetness intact), ball of cells that will become your baby has completed a week-long trip down the fallopian tube and has claimed a place in your uterus by tunneling into the uterine lining sticky. Located in the home of your womb, has formed a miniature miracle cozy relationship that will bind you both for eight plus months into the future and forever.
But that was just the beginning of this week's action. In the works is the amniotic sac that your baby will call home sweet home. And finally! ... sign you've been waiting for: the embryo begins slightly to produce HCG - just-for-pregnancy hormones that will change your urinary pregnancy test is positive positive. Official expecting you!
Although the embryo you just a small point, it has begun to differentiate into three layers, each with its own work tasks. The inner layer, called endoderm, will become the digestive system, liver, pancreas, bladder, and thyroid gland
The middle layer -. Mesoderm - will grow into heart, bone, kidney, muscle, and blood vessels. The outer layer, called the ectoderm, will develop into the brain, nervous system, skin, hair, and eyes. Hard to believe, but at the end of the fourth week of your pregnancy, all the building blocks for your baby's vital organs were still in place.
Although you may just begin to wonder if you are pregnant, you soon-to-be baby has found a home: the blastocyst has completed its journey from the fallopian tube in your womb you < p> Once there, it burrows into the lining of your uterus and implants - made unbreakable connection that will last you the next eight months (and life after it).
so small balls of cells settle in your uterus, it will undergo a large gap, split into two groups. Half of what is now called an embryo will be a son or daughter, while the other half form, your baby's lifeline -. Which channel carries nutrients and waste away until delivery
If you are 4 weeks pregnant, you're in one of your pregnancy. Just eight months to go! Still have questions? Here is some more information about the
Despite its very small size -. No more than 1 millimeter and no larger than a poppy seed (think about that when you eat your morning bagel) - tiny embryo you busy preparing the house.
While the amniotic sac (also called water pockets) form in the vicinity, as well as egg yolks, which will be entered into.
embryo now has three distinct layers of cells that will grow into a special part of your baby's body.

Just a week after fertilization, the baby-making is still in its infancy, so to speak. At 4 weeks pregnant, your body is getting ready, big-time - the transformation of a friend tried-and-true for the odd and bizarre scientific experiment
Chances are you're aware of all the hubbub .. While some women experience bad luck they, PMS-like, including mood swings, bloating and cramping, others do not feel anything.
Whatever you feel is or do not feel, probably still too early to see the results of which are unreliable in your pregnancy test. But behind the scenes, here's what happened.
The fertilized egg and womb you make contact this week, as the blastocyst you will one day call your baby starts to attach itself to the uterine wall.
up to 25 percent of the time, implantation bleeding will occur as bundles of cells burrow into the lining of the uterus. Implantation bleeding, which is usually very little and nice pink, brown, red or bright lights, occurred earlier than your expected period.
Do not mistake it for your period and do not worry about bleeding - it's not a sign that something is wrong. You may feel a little pressure on your stomach (nothing to worry about!) And your breasts may feel tender little and become larger (but get ready for explosive growth over!).
Within six to 12 days after fertilization, the egg begins to release hCG, or human chorionic gonadotropin - which horm pregnancyone that will soon change the line that on your pink or blue pregnancy test and your world upside down.
HCG alerts corpus luteum (egg follicles once released from) that it needs to survive and produce progesterone and estrogen to maintain the pregnancy until the placenta takes over about eight weeks from now.
Think you need a Ph.D. in quantum physics to know your due date? Doing the math is actually much easier than you think (even if you slept through high school algebra). Your estimated due date is 40 weeks from the first day of your last period.
Too easy? This is the part that is a little confusing. If you give birth on that day, your baby will have clocked only 38 weeks in the womb, not 40. That's because pregnancy counting began two weeks before your baby is even conceived (make you about 4 weeks pregnant before you can tell you're expecting from pregnancy test).
Want to set your clock by the due date or at least plan around your maternity leave? Not so fast. Remember, your estimated due date is just that - an estimate. Most babies born between 38 and 42 weeks (and the first babies of mothers are more likely to arrive on the later side), while only a handful of really making their debut on schedule.

Regardless, you do not have to plan your schedule around your approximate due date. After all, it was just an estimate. Most babies born between 37 and 42 weeks - the first babies of mothers are more likely to arrive at the second side. Only a handful of babies are really making their debut on schedule.
You may not smoke, but if you hang out with people who do, quit. Recent studies have found that exposure to secondhand smoke can increase the risk of miscarriage, low birth weight, ectopic pregnancy and other complications
Your baby needs some fat -. especially essential fats (which is why they are called essential), such as omega-3 fatty acids. DHA, one of the omega-3, is a major component of the human brain and retina, and it is important to develop your baby's brain and eyes.
