cope with 3rd failed IVF

Hi ladies, might I please ask you how you coped with failed IVF? I have just had a third transfer without a success :-( it is breaking my heart. Last cycle we arrived to have 8 very good quality blasts, they transfered 2. We couldn't do the pgd testing here as the clinics are doing it only after 3rd failed cycle. I know we still have 4 frozen (2 weren't good to transfer) but it is still harder and harder to believe I will ever gonna be a mum :-(
