lil_chookie, do you perhaps have PCOS? The situation you describe is a classic PCOS response - unpredictable. A dose that previously works, suddenly doesn't.

With our first cycle, we started low, got nothing... but instead of increasing slowly as your FS is doing, mine doubled the dose and sent me away for 4 days. We got a response - too much of one! I ended up with OHSS and a freeze all cycle.

Try to relax, and trust that your FS knows what he's doing, and is doing his best to avoid the horrors of OHSS. Having been through it twice, next time I'll be insisting we do it differently - start low, increase slowly, as you have been doing.

I'm certainly hoping it works out for you sooner rather than later.
