PGD I need an opinion and advice on my Los

Jasgib
Had miscarry April 5-16 , though I stop 
Taking my drugs prescribe by my doctor, estrofem .I don't know if that's the cause of the miscarry or the coffe tea I took earlier .
my last period was February 28.
I did pgd for gender selection ,and the transfer date was march 20th
My doctor blame it to the medication I stop 
And advice me to try one month time 
I need opinion on this , the date to try again too early or not ?
Thank you !
