During the twelfth week of pregnancy, the baby continues to grow rapidly – intestines are still developing but there’s enough room for them to move in the abdominal area since the baby has grown considerably in size.
Pregnancy Week by Week
The tenth week does not mark too many physical changes in the body, and you may not be showing as much as you think you are.
By week 9 the baby has officially entered the foetal period and is about an inch in size, weighing around 3 grams (just like week 8 of your pregnancy).
By the eighth week, the embryo shifts from the embryonic stage to the fetal stage. This period also sees the reduction and eventual loss of the embryonic tail.
During the seventh week, pregnancy symptoms will continue, including aches, fatigue, morning sickness, tenderness in breasts and cravings.
By six weeks, the baby’s nose, ears and mouth begin to develop and the ultrasound should be able to show you all these features quite well.
During the fifth week of pregnancy, the baby is growing quite fast. By the time you’re through the fifth week, the baby is about 1-5mm in length and resembles a tadpole (tail included).
During the fourth week of pregnancy staying hydrated is important, as it will help maintain your energy levels and keep you from fainting due to fatigue.
At the third week, the embryo is at the ‘morula’ stage, and can best be described as a spherical mass of cells that are actively multiplying. Since it is the early days of pregnancy, you need not quit your job or take a leave. You can also continue any normal activity until the doctor advises to stop or alter it.
The baby at week two undergoes sexual differentiation through the X and Y chromosomes. The second week initiates different processes that deal with fetal development, and it is important not to mend any lifestyle or dietary habits which can be detrimental to the baby’s health.
