Suggest Treatment For Endometrium

Iam planning donor embryo transfer.Mydoc advised me to take lupride injection 0.25mcg daily after the ovulation of previous cycle. In fear of ovulation in the current cycle I have taken lupride upto 0.4 mcg. Now even on the 15th day of last menstural period my endometrium is only 7mm. Even in the drug free cycle my endometrium is always good and even upto 11mm. Whether the present situation is due to high lupride or what I have to do now. My Doc advised me to wait for another 1 week.
