Hi Moomoo, Its progesterone jab, daily jab. No name leh, I bought it from KKH. Initially, my doctor prescribed me pregnyl, but I know of the side effect, so I ask for progesterone instead. Usually pregnyl would not be given to those who retrieved more than 15 eggs because it will cause more bloatedness and mine is 14 so at the borderline. But then as progesterone has the same effect as pregnyl, I opt for progesterone. But then I must have my daily jab.
