G is Gravida.. This is the number of pregnancies a woman has had..
P is Para.. This is the number of babies a woman has..

So G3 P2.. 3rd pregnancy.. 2 babies..

It gets confusing with twins and miscarriages..

G4 P1+2 - 4th pregnancy, 1 live baby, 2 miscarriages..

G3 P6 - 3rd pregnancy, 2 previous set of triplets...
