What happens in the first stage of pregnancy?
Before we begin to explain what happens in the early stages of pregnancy , we must know that pregnancies are divided into trimesters . Each trimester lasts approximately 13 weeks.
It is only in the first two weeks of the menstrual cycle that a woman has her period. Two weeks after this, the egg matures and is released by the ovary, this process is known as ” ovulation ” , which can happen earlier or later, depending on how long the woman’s menstrual cycle lasts. It usually lasts 28 days. You can check out our Fertile Days Calculator.
Once the egg has been released, it moves through the uterus, traveling through one of the fallopian tubes. (See female reproductive system ).
In the third and fourth weeks, the fertilized egg travels to the uterus , where it nests there 3 to 4 days after having joined with the sperm and divides into many cells. The dividing cells join together to form a gestational sac that lives freely in the woman’s womb for about 3 days.
A pregnancy begins when the gestational sac attaches to the uterus; this part of the process is known as implantation . It usually begins 6 days after fertilization and takes 4 days to complete.
