It seems incredible, but yes, a woman may be pregnant while she is pregnant! This rare syndrome is called superfetation and is related to the conception of a second fetus while you are pregnant with another. What will be the result ?!

A happy mother with 2 twins of age and sometimes with different birth dates.

No one knows why this is happening, but some believe it happens when embryo implantation is delayed to prevent hormones.

Lack of knowledge on this phenomenon is probably due to the fact that it is very rare. Surplus scholars have identified only 10 such cases.

This phenomenon, called "superfetation", is not the same as "superfluity." The latter involves fertilizing two eggs during a period of the menstrual cycle. Whereas, in the first case, conception occurs in different menstrual periods, therefore the twins come out with weights, lengths and blood groups different from each other.

Normally, when a woman is pregnant, her ovaries do not release eggs from the womb because the hormones lead the body signals to prepare for baby growth. However, in the case of overexcitation, the ovaries are generated, releasing another egg and thus another pregnancy is possible.

Apart from humans, this phenomenon also occurs in animals. The first to notice this in a rabbit was Aristotle. He saw that the rabbit had brought babies with different weights.
