Go for it
My friend has got an exactly similar problem last year.
In the IVs they did not ask him about his failed attempt at all, they just asked him whether his ECFMG will be ready before ranking and he promised YES and he did.
He was matched in Ob/Gyn out of two interviews only.
Do not underestimate your chances, you can make it
Prepare very well for the IV, I'd recommend you get some IV training.
Good luck
