Fet help please

Today is day 1 of my cycle however my embryos was biopsy and froze on Sept 30. I was told it takes 7 to 14 days for the results. If the transfer is happening then it would be for day 10 which I don't know if we'll have the results by then. Do you think theyll still proceed planning the transfer while waiting on the results or would they have to cancel this transfer cycle due to not having the results?

Also which cycle day would you normally start taking medication for ivf transfer?
