Fertilization Process

Starting from fertilization, where millions of sperm cells will compete towards the egg while releasing an enzyme that can make one of the sperm successfully reach its destination, the egg. During fertilization, there will be chemical changes that prevent other sperm from entering the egg.

When one of the sperm gets into the egg, the next pregnancy process is that the sperm enters the cell nucleus which carries the genetic code, then integrates with the genetic code of the fertilized egg. Furthermore, sperm determine the sex of the baby by 46 chromosomes that make up genetic characteristics.

The fertilized egg will then divide into 2 cells, and then develop into 4 cells. The egg cell will always develop. As the division of the egg continues, so does the cell that moves from the fallopian tube to the uterus. on this seventh day, where after the fertilization process took place.

Then the divided cell has reached 30 and the collection of cells is called by the name  morula . The morula that has reached the uterine lining will be embedded in the endometrial lining. This group of cells that develops will become more mature and become blastocysts, while stimulating changes in the body of the expectant mother, including the cessation of the menstrual cycle.


First Trimester
Calculation of the date of pregnancy can start from the first day of the mother's last normal menstrual cycle. Meanwhile, fertilization usually occurs in the second week. The first trimester lasts from the first week to the 13th week of pregnancy.

Although physically changes in the mother is not clearly visible, but certainly there are major changes in the body of the mother, such as hormone levels that change significantly. The uterus will start supporting the growth of the placenta and fetus. The body will increase blood supply to carry oxygen and nutrients to the developing fetus.

In this first trimester, the fetus will develop all its organs at the end of the third month. Therefore, these moments are very important to maintaining a healthy diet, including adding enough amount of folic acid to help prevent neural tube defects in the fetus.

Some screening tests are  usually done in the second trimester. Be sure to discuss your personal and family medical history with your doctor to find out genetic problems that can pose a risk to the fetus.

The second trimester also becomes a moment when fetal body parts are formed such as the heart, lungs, kidneys, and brain. Mothers can also find out the sex of the baby in the second trimester.
