5 weeks- Your baby’s body structure has started taking shape! 


This weeks is very crucial, as it marks the beginning of your baby’s organ formation.

Your baby is very tiny, hardly measures of a size of a peanut seed . It resembles more like a tadpole.

According to many researchers, its embryological development would  subsequently resemble the phases of evolution of animal kingdom.

The main changes happening in your baby are:

1- Differentiation of cells of three Germ layers to lay the foundation of specific organ formation.

2- Differential growth and folding of embryonic disc,  giving it an appearance of a tadpole.

3- Development of spaces within the baby (intra-embryonic spaces – cavities) or outside (extra-embryonic spaces like chorio-amniotic cavity, yolk sac).

4- Finger like projections (Villi) from its outer trophoblastic tissue invades into your blood vessels to form Primitive Placenta to initiate Maternal-Fetal Blood circulation.

As a result of the ongoing process of organs formation, close to completion of 6 weeks,

  • Your baby’s tiny heart develop as a tube and will begin pumping blood soon.
  • The neural tube, which connects its brain and spinal cord continue to grow.
  • The site of all the organs of the body is well established and their development begins.

How ever, you would remain unaware about these changes happening inside your womb. You may just experience early signs of pregnancy-

  • Nausea, Morning Sickness, Fatigue, Increased urination, abdominal pain etc.
  • If you experience little spotting from vagina during this phase, Don’t Panic. It may be Implantation bleeding, due to invasion of your baby’s placenta into your blood vessels. It may not cause any harm to your baby. The fetal wellbeing can be confirmed on Ultrasound.
  • Little abdominal cramps are also common during this phase. Don’t Panic! It may be because of stretching of uterus by growing fetus.
  • The ultrasonography at this point of pregnancy would establish:

1- The location of developing fetus – normal pregnancy within the uterus or abnormal outside the uterus (Ectopic Pregnancy).

2- Number of developing fetus. Single or Multiple gestational sac. If multiple, then nature of zygocity, i.e. identical or non identical.

3- Presence of fetal pole within the gestational sac, that would form future embyro.

4- Presence of a good, turgid yolk sac indicates a healthy pregnancy.

5- Expected date of delivery can be estimated from the size of gestational sac.

You are becoming the ‘Creator’ by giving birth to a life. The baby would be entirely dependent on you like a parasite. So, kindly follow a healthy life style to ensure the safety of both baby and you.
