Timetotry - I'm so sorry to hear that clomid wasn't your answer.
I'm just behind you on 7dpo and I strongly suspect I'm in the same boat. This is my 3rd and final clomid round and I really feel that although Clomid has helped me O, it has created a lot of difficulties for me TTC (my CM hasn't been good on any Clomid cycle, even with EPO, and my AF has been 3days instead of my normal 6-7days which I suspect may mean my UL has been much thinner). I have an appointment on Feb 4th to see what we'll be doing to next. Do you know when you'll see your doctor to discuss your next steps? Please keep updating with your progress - we might be IUI buddies
Sending hugs
