gravida/para

Gravida indicates the number of times the woman has been pregnant, regardless of whether these pregnancies were carried to term. A current pregnancy, if any, is included in this count.

Parity, or "para" indicates the number of >20-week births (including viable and non-viable; i.e., stillbirths). Pregnancies consisting of multiples, such as twins or triplets, count as one birth for the purpose of this notation.
