(Discover a baby’s journey from inside the Womb to into your Arms.)

Gynecologist chapter describes how your baby develops from the day you conceive to the day you give birth. by dr. pooja bansal

From conception to labour, Baby is constantly growing and developing.

Pregnancy is measured from the first day of your last menstrual period, not the day you conceive. So when you’re ‘four weeks pregnant,’ you’re actually about two weeks after conception. Pregnancy typically lasts 39-42 weeks, beginning with the first day of The last period. The average duration of time is 40 weeks.


3 Week:

  • Egg is released from the ovary 
  • Egg is fertilized 
  • Fertilised egg divides and travels down fallopian tube
  • Embryo implants itself in uterus lining


If a sperm penetrates the egg, it is fertilized. The fertilized egg will begin dividing into multiple cells as it travels down the fallopian tube, into the uterus, and begins to burrow into the uterine lining over the next few days.

4–5 Weeks:


Embryo now settles into The uterus lining. When The next period is usually due. The outer cells spread out like roots to connect with The blood supply, potentially resulting in a positive result on a home pregnancy test.

The baby is the size of a <2 mm.


6–7 Weeks:


Baby looks more like a tadpole than a human, but it is growing quickly. The circulatory system is forming, and the tiny “heart” will begin to beat this week. A large bulge where The baby’s heart is and a bump on the head because the brain is developing nose, mouth, and ears are taking shape, and their intestines and brain are developing. Baby’s features – eyes, nose, mouth, and ears – are becoming more defined. Arm and leg buds are growing  longer.

The baby is the size of a blueberry.

8–9 Weeks:


The baby’s face is gradually taking shape. The eyes are more visible and have some color. The foetus has a tongue and a mouth. Hands and feet are starting to form, with ridges where the fingers and toes will be. The heart, brain, lungs, kidneys, liver, and gastrointestinal tract are all developing.

The baby will be about 22mm long.


  • The umbilical cord:

The umbilical cord is a baby’s lifeline. It serves as the link between you and your child. Blood circulates through the cord, carrying oxygen and nutrients to the baby.


  • The placenta:

The placenta is attached to the uterine lining and separates The baby’s circulation from The circulation. The placenta passes oxygen and nutrients from the bloodstream to the baby’s bloodstream via the umbilical cord. Antibodies that confer infection resistance are passed on to the baby in the same way. Alcohol, nicotine, and other drugs can also be passed on to The baby in this manner.


  • The amniotic sac:

The baby floats inside the uterus in a bag of fluid known as the amniotic sac. The sac, or membranes, ruptures before or during labour, allowing the fluid to drain. This is referred to as the ‘waters breaking.  


10–14 Weeks:


The baby has all of his or her organs, muscles, limbs, and bones, and his or her sex organs are fully developed. The baby has begun to move, though you will not feel it. Nerve cells divide and form primitive neural pathways. Breathing tubes have now developed from their throats to their developing lungs. The pregnancy may begin to manifest, but this varies greatly from woman to woman..


15–22 Weeks:


The child is growing faster each day .

Their body expands so that their head and body are more in proportion.

The face becomes more defined, and hair, brows, and eyelashes begin to grow. Their eyelids remain closed over their pupils. As the lines on the skin of The baby’s fingers form, they already have their own unique fingerprints. Their fingernails and toenails are growing, and their hands are becoming more capable of gripping. Around 22 weeks, The baby will be covered in lanugo (A fine soft hair). Experts think it is to keep the baby at the proper temperature.

The lanugo goes away before or shortly after birth. You will usually feel The baby move for the first time between 16 and 22 weeks. If this is The second child, you may feel it sooner, around 16-18 weeks.

You first notice a tinkling or bubbling sensation, or a very mild shifting movement. This can feel similar to indigestion. You’ll be able to tell later that it’s the baby’s movements, and you might even see the baby kicking around. Sometimes you’ll notice a bump that looks like a hand or a foot.


23–30 Weeks:


The baby is now moving around a lot and responding to touch and sound.

A loud noise nearby may cause them to jump and kick. The baby can now swallow, and their digestive system is producing meconium, the dark, sticky goo that they’ll pass in their first poop – either in their diaper or during delivery in the womb.

The baby’s muscles and lungs are busy getting ready to function outside world outside the womb, and their head is expanding to make room for their developing brain.

The infant is about the size of a butternut squash.


.31–40 Weeks:


The baby is still developing. Their previously wrinkled skin smoothes out, and both the vernix and the lanugo begin to fade. The baby is usually lying with its head pointing downwards by 32 weeks, ready for birth. Before birth, the baby’s head can ‘engage,’ or move down into the pelvis. Sometimes the head does not engage until labour begins.
