Understanding Pregnancy Terminology: G11 P1 SAB 1 Explained

Question
This is for homework. If a Doctor says you are G11; P1; SAB 1, what does the SAB 1 mean: LMP 3-4-04. Thanks so much. She is 34 years old.

Answer
G11 means that she has been pregnant (including this one) eleven times. P1 means that she has come to term one time. SAB 1 means that she has one spontaneous abortion. LMP is the first day of her last menstrual period (March 4, 2004). If her last period started on March 4, then she ovulated and conceived on March 17 and is due on December 11.
