Pregnancy - General Care
The period from conception to birth is known as pregnancy and usually, lasts for nine months. After the fertilization of the egg that is done by the sperm, it is implanted in the uterus. Later it develops into the placenta and embryo, and later into a fetus. It is a period in which a woman carries a fertilized egg (that is fertilized by sperm) inside her body.
First month: At the end of the first month, the embryo is about a third of an inch long. It starts to develop its head and trunk along with certain other organs like arms and legs. It starts receiving essential nutrients that are required for the growth of the overall body structure and starts eliminating waste through the umbilical cord and placenta. In normal conditions, the end of the first month indicates the development of the liver and digestive system begins to develop, and the heart starts to beat.
Second month: In this month, the heart starts functioning and starts pumping in a normal way. The second month deals with the development of the nervous system (including the brain and spinal cord). The fetus has a complete cartilage skeleton, which is replaced by bone cells by the end of the second month. Arms, legs and all of the major organs begin to appear. There are chances that the facial features may start developing at the end of the second month only.
Third month: a healthy pregnancy will relate a fetus that has grown to almost 10 cm and weighs a little more than an ounce (28 g). The face starts to take a normal appearance and features tend to become sharper with the passage of each day. Fingers and toes appear. The four chambers of the heart are complete and the fetus shows a fully functional kidney along with other major organs as well.
Fourth month: The fetus begins to kick and swallow, but there are chances that still most of the women do not feel the moving at this particular time. The movement may be slow.
Now 4 oz (112 g), the fetus can hear and urinate and has established sleep-wake cycles. The organs are almost developed but they will continue t grow more in the next months as well. The fetus has skin, eyebrows, and hair.
Fifth month: the fetus is now 454 g and measures 8–12 in (20–30 cm).
Sixth month: Lungs are still underdeveloped but fetus born at this point in time can still survive with intensive care. The fetus now weighs 1–1.5 lb (454–681 g)
Seventh month: Fetus born during this period has better chances of surviving and may weigh around 3 lb (1.3 kg) by now. The fetus can see around the womb now!
Eighth month: The month deals with growth but there is a gradual decline in the growth process as all the organs are almost fully developed. Now weighing 4–5 lbs (1.8–2.3 kg) and measuring 16–18 in (40–45 cm) long, the fetus prepares the body to come out of the womb!
Ninth month: The fetus drops lower into the mother’s abdomen and prepares for the onset of labor, which may happen anytime between the 37th and 42nd week of gestation.
