hannah,
i'm on my second cycle with provera and clomid (100mg dose) and are going to see how this goes . when i saw my fs at the beginning of this cycle he said we had 2 options #1 keep going with provera and clomid but have 100mg instead of 50mg or #2 have provera, clomid (50mg) as well as fsh injections with bloodtests and ultrasounds to monitor when i am ready to ovulate.
i don't know what your personal situation is, but i was under the impression that iui was for couples that both have fertility troubles, not just the female.
As my dh has no troubles my fs said that if clomid doesn't work by itself then he said that the fsh injections by themselves should hopefully work for me. otherwise i think my dh and i will be looking at ivf, due to the severity of my pcos.
hope this helps you out.
