just wondering if anyone has and advice on when the right time to change FS is? We are on our forth cycle, 1st was cancelled,2nd five eggs all bfn, 3rd 2 eggs bfn, 4th in danger of being cancelled, I am just losing hope with our FS and even though he is really nice we still do not have our BFP! Going crazy and feel like this is taking its toll on me! The only saving grace is that my dh and I are stronger than ever. He is truly amazing!
