I posted something similar about day 3 or day 5 transfers... with all my previous transfers - 4 in total - we used 7 day 3 embryo's which resulted in a chem pregnancy from our fresh transfer, a BFN on our first FET, an ectopic pregnancy on our second FET and a very much alive and kicking baby girl with our 3rd FET.
I'm now cycling for hopefully no #2 and have chosen this time to use my day 5's to see what result we get with them. But as you can see we have had some form of success from all bar 1 of our day 3 transfers. Don't know if this helps but I can truly understand the dilemma you are facing.
