My first cycle was cancelled, although I did make it to EPU and had 4 eggs collected. However, none fertilised so didn't get any further for that one. Subsequently my FS increased my dose of Gonal F. I've now done 7 cycles (if you count 1xIUI and 1xFET) and the protocol has been quite different in every cycle, although most of the time I've still been on Gonal F 450. I've had different things introduced, such as Luveris injections, which I remember because I think that was my most successful cycle (most eggs fertilised). There seems to be quite a few different protocols that can be tried, so if it's appropriate I'm sure your FS will change it. As for me, I will try one more cycle with my current FS as she wants to try steroids and Clexane, but if I have no success with that I'm going to change FS. So if you find yourself at a dead end trying the same thing over and over again without success, you also might want to consider a second opinion.
