Suggest Precautions To Be Taken For Successful FET Implantation

Hi Doctor,

I have undergone IVF treatment which has resulted in BFN. ER 12 eggs and 11 were fertilised and only 2 reached day 5. Doc did ET one 5day embryo and said its good quality and i was put on progesterone(chrinone 8mg gel) However, i started by period exactly 14days after egg retrival. I took one month break and planned by FET with 5day embryo next month.
I do not have any history of problems and my husband sperm count is good as well. Dnc was performed 6 months before. HSG showed that both tubes are normal.

please advise any mesures to make my FET implantation successful.
