hi wishes... I too have just had a cycle cancelled, due to no response to synarel, and I also feel really down and disappointed! Last week when I was meant to start injections they said my oestrogen was too high, and to stay on the synarel an extra week (which is what happened in my first cycle, and I responded after the extra week)..but at the next blood test two days ago, my hormones had risen (doubled!) and it appeared I was close to ovulation, so the cycle was cancelled. And same as you, I have been told to simply wait for a period, then we'll go again, using the same approach. I am not too confident about simply repeating things. My nurse also said Lucrin was very expensive.
I can certainly relate to that feeling of being so close, after 5 weeks, on the pill, and sniffing synarel (not to mention the general ups and downs of the past year leading to this)..to then have the rug pulled out from under me, and right back at the start.
I really wish you all the best for your next go.

And thanks everyone who has responded..it also helps me!
