After getting pregnant, the body will start going through significant developments from month to month. Pregnancy lasts for nine months, starting from the day of conception to the day of delivery. Although the earliest symptoms may differ from person, the general rate of change remains the same and can be divided on a monthly basis as follows.
The first month is accompanied by a huge change in the hormonal balance of the body. There will be an increased secretion of estrogen and progesterone as well as HCG or the human chorionic gonadotropin. This will cause breast tenderness, nausea and fatigue and a need to urinate frequently. The pregnant woman will also experience food sensitivity that is a craving for certain food items and an aversion to the others.
During the first month, the baby will still be in the blastocyst form but the gender will already be decided.
During the second month, the baby will transform from the blastocyst form to a zygote form. It will start taking a more human form. This period will again be accompanied by intense fatigue and nausea. The expectant mother may also experience moodiness and emotional fluctuations due to the change in hormone levels. At this stage, it is necessary to start making necessary changes to the body for the healthy development of the foetus. Smoking, drinking, alcohol and caffeine should be strictly avoided.
The third month is the end of the first trimester. By this time, the baby will officially be a foetus. It will have developed all the organs and the nails will start taking form. The baby may also start making movements although it may be not very much noticeable. The third month will also see a shift in the hormone levels.
By this time, the baby will be five or six inches long. The heart is fully formed and the lungs are till forming. The nausea and fatigue will also fade away and there will be a rise in the energy level.
The baby is now six to ten inches long and weighs 10 pounds. Finger prints and teeth are fully formed and if it is a girl child, the ovaries will start developing. This is a great phase as the belly is not so huge and there is minimum physical discomfort.
This time the baby is fully formed and going through the final finishing touches like eyebrows. The baby will also start showing considerable physical movements.
This period is marked by a rapid development of the brain. The baby can see, hear and feel. Fats starts to get stored under the baby’s skin and the foetus will start to look more like a baby. The mother will start to feel muscular pain and cramps as well as softening at the joints.
By this time, the baby will weight over a pound and the mother will experience some weight gain. As the baby fills up the uterus and starts descending into the pelvic area, movements will slow down. The mother may experience heartburns and get stretch marks. This is the time that delivery planning should be done.
By now, the baby should be 18 to 20 inches long and fully developed. The brain however, is still growing. The mother may experience intense bursts of energy one moment and feel totally exhausted the very next. By the end of the ninth month, the uterus will start contracting, the foetus will be pushed down and the mother may start experiencing labor pains.
