day 3 transfer delayed to day 5

Jessica
On day 3 we got the call to say we have 3 great (two grade 1 & one grade 2) embroyos. The doctor only expected 2 out of 3 fertilized might make it to day 3 which is why she scheduled a day 3 transfer. 
In the car already for my appointment they suggest we cancel and wait until day 5! I hope at least one of my embroyo's makes it to transfer! This is such a nerve wracking process. 
Anyone else have only a few embroyos day 3 and choose to wait to transfer on day 5?
