Explanation:

Abortion is a very traumatic situation in a woman's life and is characterized by an early termination of pregnancy before 20 weeks. Abortion or, more correctly, abortion is the early termination of a pregnancy before the fetus can survive outside the mother's body. Abortion can occur intentionally or completely spontaneously, in both cases being a painful process for the woman living in this moment.

The World Health Organization (WHO) presents some criteria for the termination of pregnancy to be considered an abortion. According to WHO, abortion is considered interruption before 20 weeks of gestation, in which case the fetus is usually less than 500 g. When the fetus is removed under these conditions it is unable to survive outside the mother's womb.
