Oh Night Nurse - my heart is broken for you. Yes, your odds if you have 5 should really be 50/50, so you should technically have one or two girls in there. What an exhausting process it is.
If I were you, with everything you have been through, I would talk to the RE about another cycle free of charge with the exception of meds. I know they are human beings and make mistakes, but a machine making a mistake in a process like this? They are dealing with people's lives and emotions here. I would think that knowing what you have been/are going through, your RE would comply.
I will say a prayer for you. Kiki Jane
