Emma I am so sorry you lost some more. I think it depends on the clinics and what they think is best at the time depending on each individual circumstance. I am hoping you won't be needing the ones in the freezer. I agree with Amy jellybean don't be to hard on yourself. I ask my clinic everything so I can understand the divisions they make.
Maybe have a chat to them and they might be able to explain why they wanted them to go past day 2/3.
Sending you a big hug xo
