The First Trimester – Conception – 12 weeks: Changes in Baby
2 – 4 weeks
The remarkable thing about pregnancy is every day is a new day and as a pregnant woman, you will be able to closely observe the changes every week. The first 2-4 weeks, you may not even know you are pregnant yet because you have not yet missed a period. The first 2-4 weeks is the beginning of a new life in you. The embryo is a group of cells and growing at a rapid pace and at this stage is nothing but the size of a small pinhead.
Many women now first suspect a pregnancy because a period is missed and a pregnancy test can confirm it. From the 5th week onwards, your baby begins to develop a plate, which will later become the heart. Other major organs, including kidneys and liver, begin to develop and the neural tube (which connects the brain and spinal cord) closes.
9 – 12 weeks
Now your baby has fingers and toes, while nails too are growing. Hair is growing too on your baby’s body. The fetus weighs about 15 grams now and is about 2 inches long! Go ahead and imagine a teeny tiny fetus with little little fingers.
First trimester: Conception to 12 weeks – Changes in Mother
Some women complain of heavy morning sickness and throw up at the sight of food. A few others are lucky and pass this phase without much discomfort, though most women throw up a few times. Some kind of smell may become intolerable and this experience again is different for each woman. Fatigue and nausea go hand and hand in the first trimester and this may be due to poor intake of food. It is important to eat small meals throughout the day to avoid fatigue and important to avoid probable anemia. This may be the point when you start feeling heaviness in your breasts. Rest is important at this stage.
