How Pregnancy Happens ?

How Pregnancy Occurs



Understanding how pregnancy occurs is important. Even if you want to avoid pregnancy, this section helps to know when a woman is more likely to become pregnant and when she is not.

Pregnancy occurs when a fertilized egg implants in the uterus and this can happen in various ways and methods. Understanding fertility patterns can help with getting pregnant as well as avoiding pregnancy.


Process of Pregnancy



For a woman to get pregnant, she must release an egg from her ovary at the time of ovulation. The egg and sperms then meet and form a single cell for fertilization. Then pregnancy begins if the fertilized egg attaches to a woman’s uterus and starts to grow.


Menstruation

Women will have her periods during the first two weeks of her menstrual cycle. The bleeding usually lasts for 3 to 7 days. After which, the hormones make eggs to mature in her ovaries and the lining of her uterus starts thickening.

Ovulation

Ovulation occurs about 2 weeks before a woman’s next period. The egg enters into fallopian tubes and then starts moving toward the uterus.

Fertilization

After a vaginal intercourse or insemination through any methods, several hundreds of sperms travel through the uterus and into the fallopian tubes. An egg may be in one of the fallopian tubes and one sperm may fertilize the egg. The other sperms may seep out of her vagina or are absorbed in her body. The joining of an egg and sperm is called fertilization. This occurs most likely on the day of ovulation or during the five days before an egg is released.

Implantation

The fertilized egg then moves down into the fallopian tube and divides into more and more cells forming a ball. The ball of these cells reaches the uterus about 3 to 4 days after the fertilization. The ball then floats in the uterus for about another 2 to 3 days.

Pregnancy begins when the ball of cells attaches to the uterine lining. This is called implantation usually starts about 6 days after fertilization and takes about 3 to 4 days to be complete. The embryo then is developed from cells on the inside of the ball and the placenta is developed from the cells on the outside of the ball.  More than half of all fertilized eggs never implant and they pass out of women’s bodies during her menstruation.
