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 Fallopian tube and is available to be fertilized by meeting a sperm). Now your partner’s sperm will meet your ovum and the fertilization will occur. If this is successful then you are Pregnant! So, from this week on wards, your baby will start to form. You have conceived.
The surprising fact is out of millions of sperms 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 sperm’s nucleus and get transformed into a genetic material. Once an egg gets fertilized, it is to be known as ‘zygote’. (For healthy zygote your ovum should be of an adequate size i.e. 16mm-20mm. This in further lead to healthy pregnancy and chances of abortion are decreased.)
Within the hours of fertilization, a zygote, moves from Fallopian tube to a uterus. This zygote is now divided into 16 identical cells. These cells are somewhere yellowish in color and are known as Corpus Luteum. These cells will produce required pregnancy hormones which are progesterone and estrogen to support your pregnancy till more 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 as Blastocyst.
The movement from Fallopian tube to the uterus can take six days, hence implantation starts from the 4th week. From here, the middle of the cell will become embryo and amniotic sac. The outer part of the cell mass will turn into 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 baby girl.
