is a glowing, mum-to-be with a full belly. While this is right, it is not the full story – it’s the abridged version.
There’s a lot more to pregnancy than that dumbed-down simplification. Pregnancy is complex and miraculous, and knowing what is really going on gives you genuine and awe-inspiring appreciation for the human body and what it is capable of.

a pool in the vagina near the cervix. This is called the seminal pool. The location of the pool is right blow the uterus, in an indentation in the vaginal wall. Here, semen wait to go into the uterus.

to descend from the ovaries. If a woman is not ovulating when the sperm are in the fallopian tube, then there will be no egg to fertilize and they will simply die away.

sperm will fertilize it, rather than the other way around. The previous theory stated that it was survival of the fittest i.e. only the strongest sperm that made it past all the others would fertilize the egg. But studies are uncovering that the egg determines which sperm is just right and only allows the chosen one to fertilize it.

called the pre-embryo. After about 4 days, it will implant itself on the uterine wall. This process can take a couple of days or up to a week. We’re getting closer to the actual pregnancy now

to release hormones that prevent menstruation from occurring. So it is effectively shutting off the body’s ability to produce more eggs for fertilization. This is why your period stops during pregnancy

pregnancy is said to have begun. Now all your reproductive systems efforts will be focused on nourishing and protecting the embryo.

an embryo for about 6 to 8 weeks, after which it will be called a foetus. A human female will carry the embryo and foetus for approximately 38 to 42 weeks or around 9 months before she gives birth to a baby. This carrying of the foetus in the womb is what pregnancy is about. So as to more conveniently calculate the date of birth of the baby, pregnancy may be assumed to begin from the date of conception rather than from the date of implantation, since it is difficult to know when the latter occurs.

different, and wondering whether you might be pregnant? The most common early signs and symptoms of pregnancy might include: -Missed period -Fatigue -Smell sensitivity -Morning sickness (nausea) -Food aversions -Mood swings -Tender, swollen breasts -Darker, bumpy areolas -Frequent urination -Bloating -Raised temperature -Bleeding

normal, including behavioral, cardiovascular, hematologic, metabolic, renal, and respiratory changes. Increases in blood sugar, breathing, and cardiac output are all required. Levels of progesterone and oestrogens rise continually throughout pregnancy, suppressing the hypothalamic axis and therefore also the menstrual cycle.

about three months. Each trimester is defined as 14 weeks, for a total duration of 42 weeks, although the average duration of pregnancy is 40 weeks. While there are no hard and fast rules, these distinctions are useful in describing the changes that take place over time.

SECOND TRIMESTER Weeks 13 to 28 of the pregnancy are called the second trimester. Most women feel more energized in this period, and begin to put on weight as the symptoms of morning sickness subside and eventually fade away. The uterus, the muscular organ that holds the developing fetus, can expand up to 20 times its normal size during pregnancy.

is not until the second trimester that movement, known as quickening, can be felt. This typically happens in the fourth month, more specifically in the 20th to 21st week, or by the 19th week if the woman has been pregnant before. It is common for some women not to feel the fetus move until much later. During the second trimester, most women begin to wear maternity clothes.

throughout the pregnancy. The woman's abdomen will transform in shape as it drops due to the fetus turning in a downward position ready for birth. During the second trimester, the woman's abdomen would have been upright, whereas in the third trimester it will drop down low. The fetus moves regularly, and is felt by the woman. Fetal movement can become strong and be disruptive to the woman. The woman's navel will sometimes become convex, "popping" out, due to the expanding abdomen.

than babies born either before or after this range. This special time period is called "full term”. Whenever possible, waiting for labor to begin on its own in this time period is best for the health of the mother and baby. The decision to perform an induction must be made after weighing the risks and benefits, but is safer after 39 weeks.
