A Complete Information Guide on Pregnancy Week 3

Congratulations! You have made a baby. Finally, the moment has arrived, you have been waiting for…!!

As in the previous week, ovulation occurred. (Ovulation is a time when a mature egg/ovum is released from an ovary, pushed down via the Fallopian tube and is available to be fertilized by meeting a sperm). Now your partner’s sperm will meet your ovum and fertilization will occur. If this is successful then you are Pregnant! So, from this week onwards, your baby will start to form. You have conceived. 

The surprising fact is out of millions of sperm only one sperm can meet an egg/ovum. The meeting of sperm and ovum is necessary to fertilize further. 

Note: Once the sperm is able to fertilize an egg, Pregnancy starts.

Fetal Development in Pregnancy Week 3:

It takes nearly about 10 to 30 hours to get an egg fertilized by merging with the sperm’s nucleus and getting transformed into a genetic material. Once an egg gets fertilized, it is to be known as a ‘zygote’. (For a healthy zygote your ovum should be of an adequate size i.e. 16mm-20mm. This further lead to a healthy pregnancy and the chances of abortion is decreased.)

Within the hours of fertilization, a zygote moves from the Fallopian tube to the uterus. This zygote is now divided into 16 identical cells. These cells are somewhere yellowish in colour and are known as Corpus Luteum. These cells will produce the required pregnancy hormones which are progesterone and estrogen to support your pregnancy for more than ten weeks, till the placenta is completely formed.

In Pregnancy Week 3:

  • Size of baby- 0.01 inches (0.25 mm)
  • Weight of baby- Still too small to weigh
  • Baby is like a Pinhead and to be termed a Blastocyst.

The movement from the Fallopian tube to the uterus can take six days, hence implantation starts in the 4th week. From here, the middle of the cell will become an embryo and amniotic sac. The outer part of the cell mass will turn into the placenta.

Note: Please remember, the baby is a boy or girl, the whole thing depends upon the sperm of a male partner. If the sperm carries a ‘Y’ chromosome, then you will deliver a baby boy, but if the sperm carries an ‘X’ chromosome then you will give birth to a baby girl.
