G (Gravidity meaning number of pregnancies)
Her gravidity is 4 (Three previous pregnancies and 1 currently)

T (Term deliveries >/=37 weeks – 42weeks)
She had 2 deliveries within these weeks, so Term delivery is 2

P (Preterm deliveries <37 weeks)
She had 1 delivery at 34 weeks (less than 37 weeks), so Preterm delivery is 1

A (Abortion)
No record of abortion, so it's 0

L (Living)
Note that multiple gestation (twins and the likes) counts individually.
So, L is 4

Therefore, G:4, T:2, P:1, A:0, L:4

Since the twin are separate with separate names will make it a para4 with the 2 previous children
But there pregnancy is a single gravid carried same time so the previous two pregnancy 2 the twin pregnancy 1 and the present pregnancy 1
Once the deliver the baby she is carrying will make her G4P5
