Wazbub I think you aren't too young. It's a reality thing. You've well and truly tried and those rggs aren't going to get better.
I applaud your sensible approach and your choice to do what it takes to realise your dream.
I'm 44 this year and did 5 cycles with my own eggs last year. I wanted to go donor after 2 cycles but ashamedly got sucked into the hype even though I knew the reality. 12 months on from starting treatment I am proudly 3 months pregnant because I took the initiative to do what would give me the best chance of success.
I'd recommend Cspe Town as the donors are gar younger than what is available in Australia and the system is relatively straight forward and well established. Good luck.
