Pregnancy facts are the same for every woman. From egg to embryo the journey of delivering a baby happens in the same way for every one. Women release an egg once a month from an ovary into the fallopian tubes. The egg is fertilized after sexual intercourse when sperm move out of the vagina and make their way through the cervix and uterus to the fallopian tubes. Just one sperm is all it takes to fertilize an egg.

Once the egg is fertilized by the sperm it is called a zygote. The zygote will divide many times to form a ball of cells that turns into the blastocyst that is a hollow ball of cells. Hair-like cilia move the blastocyst into the uterus where it implants in the uterine wall.

The uterine wall is where the embryo and the placenta will form. The placenta will form villi, or tiny projections, that will develop blood vessels to connect the mother’s blood with the embryo. While the embryo is developing, it will float in a sac of amniotic fluid. The amniotic fluid will help protect the embryo and give it a safe place to grow.

From there the journey will take another 36 weeks for the embryo to grow to a fetus and then to a healthy baby. By the end of the pregnancy the baby will be sharing 1/5th of the mother’s blood through the growth that takes place in the first 8 weeks after conception.

Other pregnancy facts show that women will all go through the same changes during a pregnancy. While some may put on more weight than another will, their bodies will all cause changes to the body that can be expected. Just remember that soon after having the baby most of this will disappear.

While a woman is pregnant, her heart will be pumping much more blood than normal. The increase in the production of blood starts at about 6 weeks into the pregnancy. The heart rate will increase as a result of the increase in blood. This normally slows down around the 30th week mark of the pregnancy.

Other major organs are working harder throughout the pregnancy as well. The kidneys are forced to work harder because of the increase of blood they now have to filter. It’s twice as much blood as normal. The lungs are working differently because of the increase of the hormone progesterone found in a pregnant woman. More oxygen is needed during a pregnancy for both the baby and the mother.

Weight gain is a pregnancy fact that women cannot avoid. There is a certain amount of weight that must be gained to keep the baby healthy. Most women are told they should gain a certain amount of weight for their height and weight. Your doctor will be able to give you an appropriate amount of weight that you should gain during your pregnancy.

While everyone’s pregnancy is different, the babies and changes the body will go through are similar for women everywhere.
