Answer

Early pregnancy loss is estimated to occur in 10% of all clinically recognized pregnancies, with about 80% occurring in the first trimester. [1] The term "abortion" is commonly used to mean all forms of early pregnancy loss; however, due to the polarizing social stigma assigned to this term, the term "miscarriage" is used here to indicate all forms of spontaneous early pregnancy loss or potential loss. One of the common complications of pregnancy is spontaneous miscarriage, which occurs in an estimated 5-15% of pregnancies. Spontaneous miscarriages are categorized as threatened, inevitable, incomplete, complete, or missed, and can be further classified as sporadic or recurrent (>3 occurrences).
