Embryo transfer in ivf

Patient: Hiii’ve done my embryo transfer last week it was 5 day transfer and i took 6mg of bromazepame about half an hour before cause i was soo nervous. before i took it i searched on internet and found many clinics give valium before ET and some papers said it help relax the uterus. i know that both are benzo but bromozepame is of shorter half life. but i’m worried and wanna be sure it will not hurt the embryosthanks
